The crop of grapes was very light and in only a few favored localities ripened before killing frosts. Plums, except in a few instances, were a failure, the exceptions being in case of the Hansen hybrids.

While more varieties of apples are successfully grown in this vicinity than elsewhere in the state, and some correspondents recommend a long list, my experience and advice is to set only a few varieties of known commercial value, and while far too many early apples are being grown, this condition is better than planting winter apples of unknown hardiness and quality. The Northwestern Greening is the most profitable winter apple here, but I understand it is not hardy in some localities in the state.

ALASKAN BERRY HYBRIDS.--At the Sitka Experiment Station in Alaska a strain of hardy strawberries is in the making, the result of crosses between the native of the Alaskan coast region and cultivated varieties. Several thousand seedlings have been grown, all very vigorous and most of them productive and of high quality. The native variety of the interior of Alaska is now to be used in similar crosses.

The Cuthbert raspberry has been crossed with its relatives, the native Salmonberry (_Rubus spectabilis_ Pursh.) and the Thimbleberry (_R.

parviflorus_ Nutt.). The only interesting fact so far developed is that the hybrids of the two species first named are almost entirely sterile.

From the answers received on blanks sent out I find there was a fair crop of apples raised throughout this district, with the trees in good condition for winter. Wood is well ripened up, leaves all shed and plenty of moisture in the soil.

[Ill.u.s.tration: A productive strawberry field at P. H. Peterson's At.w.a.ter fruit farm.]

All report none or very little blight this year. Spraying is not done generally, but those few who do it are getting results. In our own orchard, which was sprayed twice last spring, we have not found one wormy apple.

Plums, none or a very few. Mr. Bjornberg, of Willmar, reports the Surprise plum a full crop, others a total failure. Compa.s.s cherry bore a fair crop, but with me it rotted badly, as also did Prof. Hansen's plums, Sapa and Opata.

Grapes: Not many are grown except the Beta, which bore a heavy crop in spite of the late spring frosts.

Blackberries: Nothing doing.

Raspberries and strawberries were a light crop. Strawberries especially were badly damaged by late spring frosts--with me they were nearly a total failure except the everbearing, which gave us a good crop. And I want to add that they are here to stay for home use, and possibly as a market berry. Plants are fully as hardy as the June-bearing sorts. No matter how many times the blossoms are frozen off in the spring they will come right out again and give us berries until it freezes up in the fall.

Currants and gooseberries were a fair crop.

From the reports I gather that less nursery stock has been planted here than usual, but with good results, as the season has been favorable for plantings.

The fruit list recommended by the State Horticultural Society can be relied on in this locality.

There is a good deal of interest shown here in top-working the better quality winter apples onto hardy trees with good results, and the Hibernal seems to be the best stock to use--it certainly ought not to be planted for any other purpose. The apple is a drug on the market, and those who planted largely of this variety find it difficult to dispose of the crop at any price.

STUDYING FRUITS IN ILLINOIS.--Many seedling apples are being grown at the Illinois Experiment Station. Reciprocal hybridizations between standard orchard varieties and various species of the genus Malus have been made, fifty-seven species and varieties which are not of commercial importance having been obtained from the Arnold Arboretum at Boston. Direct improvement through these violent crosses is not antic.i.p.ated, but it is hoped to acquire valuable information regarding the affinities of the various species used, and also to produce material for use in back crossing. Reciprocal crosses between standard orchard varieties are also being made in large numbers, while a difficult piece of work has been attempted in the reciprocal crossing of different strains of the same variety, and different individuals of the same strain. C.S. Crandall writes: "This project has aimed at the selfing of particular individuals, and the use on trees here of pollen from trees of the same variety in orchards 100 miles away and grown under quite different conditions. Considerable effort has been expended in the prosecution of this project, but up to the present time we have recorded no successful pollinations. We have not as yet a very wide range of varieties, but as far as we have gone we have encountered complete sterility in the selfing within the individuals and in the attempt to use pollen of the same variety brought from a distance. The unfortunate feature about all the hybridizing work with apples is the mongrel character of the plants on which we work. We know nothing of the parentage of any of our varieties, and it seems quite useless to speculate on what the segregation of characters may be in crosses between different varieties. A further discouraging feature in apple breeding is the long period required to get results from any particular cross. Effort is being made to shorten this period by grafting scions of hybrid seedlings on dwarf stocks and growing the plants in pots. This will help some, but at best the attainment of results is some distance in the future. We are endeavoring to maintain a reasonably complete record of every step that is taken so that a complete history may be available for those who may later continue the work.

"In pursuing the projects as outlined above there are a number of minor problems that are receiving some attention: such as the retention of the vitality of pollen, the period of receptivity, the seed production in hybrid fruits, and the time for and percentage of the germination of seeds. On all of these points we are acc.u.mulating considerable information that it is hoped may be of some practical value."--Journal of Heredity.

Spraying the Orchard.

HON. H. M. DUNLAP, SAVOY, ILLS.

I don't know whether I am out of place with this topic of mine or not with a Minnesota audience, but I came through the exhibit rooms as I came up to the hall, and whether you spray or not you certainly need to, for I saw all sorts of fungous diseases upon your fruit. I presume that these are not the poorest specimens you have--very few people, you know, bring the poorest specimens they have to an exhibition place, Mr.

President, and I presume that if these are the best you have the poorest must be pretty bad in the way of fungous diseases.

Of course, people don't like to have their faults told them, but if we have anything the matter with us it is best for us to find out what the matter is and then get rid of it. It is better than to do as many did in the commercial fruit-growing states a number of years ago about the San Jose scale, those that were interested in having that fact suppressed, or at least thought they were interested in having the fact suppressed that they had San Jose scale within the confines of their state. They didn't want that information to get out, so they didn't discuss the matter of San Jose scale in their societies.

In Illinois we took a different view of that proposition, and it was, that we had the San Jose scale and we thought the thing to do was to stamp it out, to get after it. So we agitated that subject in our society and talked about it. We had the state entomologist canva.s.s the entire state to find out where the San Jose scale was doing its work and gave him authority to go in and spray those places or cut down the trees and get them out of the way. The effect of that work is very evident.

The people of other states would point to us saying that they did not have the scale but that we had because we reported the fact, but I know they now have it a great deal worse than we do because of this neglect.

In this matter of spraying and spraying materials, if we go back in history--we have to look for truth wherever we find it, whether it comes from low or high sources. As a matter of fact thieves and sheep ticks and ignorance are largely responsible for our spraying and the spraying materials of today. It doesn't sound very well in a scientific body to talk that way, but truth is truth wherever you find it, whether it comes from the university professor or from the farmer. If we recognize truth, from whatever source it comes, then we are open-minded and can take advantage of things that will be greatly to our benefit.

In the matter of spraying materials: They were discovered through accident, in an effort to prevent thieving in the vineyards of Bordeaux, France. It seems that workmen on the way to their places of employment were in the habit of foraging on the vineyards of the farmers along the way. To prevent that some of the fruit growers conceived the idea it would be a good thing in order to scare them to get blue vitriol and mix it with water and spray it on the fruit along the roadside. Later in the season, very much to their surprise, they found that the grapes that were treated in that way were not affected with the brown rot. So they tried it again to see whether they were right about that being the cause, and it wasn't long before they used it for that purpose. They stopped the thieving, but they also discovered a scientific truth, that the Bordeaux mixture was a fungicide and that fact has been of immense value to the world since then.

When the San Jose scale came into this country from the west, some man who had used sheep dip for sheep ticks, said: "If it is a good thing against sheep ticks, why isn't it good against this little vermin they call the San Jose scale?" He tried it on the trees, and he found that it was an effective remedy for the San Jose scale. So we have lime-sulphur today as one of the spray materials in very common use.

Among other things the scientists told us we couldn't use lime-sulphur and a.r.s.enate of lead together, that they would have to be sprayed over the orchard in separate sprays, that is, we would have to go over the orchard with lime-sulphur and then again with a.r.s.enate of lead, that when you combined the two the chemical combination was such that it deteriorated the lime-sulphur. Some farmer who didn't know about that scientific proposition determined to put them both on together, and he found that it not only worked all right but that the two were really more effective when combined than if put on separately. So you see it was thieves, sheep ticks and ignorance that are responsible for three of our most successful ways of spraying at the present time.

Now, scientific men have come in and given us a great deal of information along various lines in regard to spraying, and I don't decry science in any sense at all. These men, while they were not scientifically educated, discovered scientific truths, and it is truths we want after all.

Just what your position on this spraying proposition is here in Minnesota, whether you have commercial orchards up here or not, I have not been able to discover. I presume that your plantings here are very largely that of the farmer and amateur rather than the commercial orchardist. In Illinois we have our large commercial orchards, and we have gotten beyond the question of whether it pays us to spray or not.

For a man to be in the commercial apple business in Illinois and not spray means that he doesn't accomplish very much and his product doesn't bring him any profit.

Now, whether you spray commercially or whether you spray for your family orchard in an amateur way, it doesn't matter so far as the spraying is concerned--you should spray in either case. If you have a community where you have few orchards and they are small, it behooves you to get together and buy a spraying outfit, combine with your neighbors and buy a good spraying outfit, and then have some man take that matter up who will do it thoroughly in that neighborhood and pay him for doing it. In that way, if you hire it done, it doesn't interfere with your farming operations and gets your spraying done on time. I have noticed this with stockmen and with grain farmers, men who are not directly interested in fruit but combine it with their regular business, that they consider fruit growing a side line and such a small part of their business that they usually neglect it altogether. In the matter of the spraying they keep putting it off until tomorrow. When the time arrives for spraying you must do it _today_ and not put it off until tomorrow.

Time is a very essential element in spraying. To give you an ill.u.s.tration: A few years ago, in spraying a Willow Twig orchard, consisting of eighteen rows of trees, I sprayed nine rows of those trees, or about half of the orchard, we will say, the first part of the week, the first two days. And then there came on a two or three days'

rain, and the balance of those eighteen rows was sprayed the very last of the week or the first of the following week. The two following sprayings went on just at the right time for them, but when it came to the harvesting of that crop the trees that were sprayed first, that were sprayed immediately after the bloom fell, produced 175 bushels of very fine No. 1 fruit, free from scab, while the other nine rows, equal in every respect so far as the trees are concerned and the amount of bloom there was, produced seventeen bushels of No. 2 fruit, no No. 1 fruit at all.

The Willow Twig is one of those varieties that is very susceptible to scab, and of course this is a marked ill.u.s.tration of what happens if you don't spray at the right time. Notwithstanding the fact that the nine rows, the last ones, I speak of, were sprayed with the two following sprays at the same time that the other part of the orchard was sprayed, the results were entirely different because the first spraying, which was really the important one so far as the scab is concerned, was not put upon the tree at the right time.

The scab fungus, which seems to appear on your apples out here, is one of the most insidious diseases we have in the whole fruit industry. I think that scab fungous disease is probably the one that affects you the most. Now, scab fungus will not be noticed particularly in the spring of the year. The time that those spores are most prevalent, the period of their movement as spores in the atmosphere and the lodging upon the fruit, is right at the beginning, right about the time of the blossoming or immediately following. For a period of about two weeks at blooming time and after is the time that you have that condition.

And the trouble is--it is just like typhoid fever. You let typhoid fever get into a family, and they do not think anything of it except to take care of the patient properly if he has it, but it doesn't scare the neighbors, it does not interest them. But let the smallpox break out in a community, and everybody is interested and scared to death for fear they are going to get the smallpox.

Well now, as compared with things of a fungous nature, the scab is a good deal like typhoid fever. The latter is insidious and it will destroy more--I take it there are more people die in the United States of typhoid fever every year than die of smallpox, ten to one. I haven't the statistics but I have that in mind, that it is a fact that they do, and yet there isn't half the fuss made about typhoid fever that there is about smallpox.

Now, that is so about the scab fungous disease. In Illinois, to ill.u.s.trate, we have what is called the bitter rot fungus in the southern part of the state. If any one has the bitter rot they are scared to death, they think they are suffering untold misfortune. The bitter rot attacks the apples when nearly grown. The ground is covered with the rotted apples, and you can see them in the trees, but this little bit of scab fungus, they do not seem to notice that.

The reason is this, that scab comes from very minute spores that appear upon the apples in May or June, and as the summer advances they spread more and more. It depends, of course, upon the amount of moisture there is present, but it begins its work when the apples are very small. If it gets upon the stem of the apple it works around the stem and the apple drops off, and you have apples dropping from the time they are the size of peas until the very last of the fall, and while it looks in the month of June as if you are going to have a good crop of apples when it comes harvest time your crop has diminished greatly or to nothing, and you wonder where it has gone. With this scab fungus they just keep dropping, dropping, all through the season; whenever you have a little rain or wind these apples that are affected will drop off. You don't notice them very much because they go so gradually, one at a time or so, and you don't notice you are having any particular loss until it comes fall, and you find that your crop is very small.

That is why I say, you should wake up to the fact that it is necessary for you to spray if you are going to have perfect fruit and plenty of it--and I doubt not you could increase the amount of fruit you have in the State of Minnesota by ten times in one year by simply spraying your orchards thoroughly at the proper time with fungicide.

To do this, as I said, you must have a spraying outfit, individually or collectively, in your neighborhood, and if you get one individually you can take the contract to spray your neighbor's trees, if you wish, and get back enough to pay you for the outlay. If you have only a few trees and you have some one who understands it, you could just as well spray a few other orchards in the neighborhood and get your spraying done for nothing in that way, charging them enough to cover the cost and enough for some profit. That is done in some sections and is a very satisfactory way.
