This species of aphids are easily killed in the adult stage by certain contact sprays. Winter applications of lime sulphur cannot be depended on to destroy eggs. Poison sprays such as a.r.s.enate of lead are not eaten by this type of insect, and consequently are ineffective remedies for aphids. Kerosene emulsion is effective but is uncertain in its effect on the foliage of the trees. The best available sprays are the tobacco decoctions, of which the one most widely in use is "Black Leaf 40," a proprietary tobacco extract, made by the Kentucky Tobacco Products Company, Louisville, Kentucky. This material is used at the rate of one gallon in one thousand gallons of spray. It may be combined with lime sulphur, lime sulphur a.r.s.enate of lead, Bordeaux, or Bordeaux a.r.s.enate of lead, not with a.r.s.enate of lead alone.

The ideal time to spray for these aphids is just as soon as all or nearly all the eggs appear to have hatched. Observations made in the University orchards this season indicate that all the eggs hatched before the blossom buds began to separate. After the leaves expand somewhat and the blossom buds separate, the aphids are provided with more hiding places and are more difficult to hit with the spray.

Unfortunately, spraying at this time would require an extra application in addition to the cl.u.s.ter bud (first summer) spray (made for scab, curculio, bud moth, spring canker worms, etc.), and would thus add seriously to the cost of the season's operations. Spraying for aphids at the time of the cl.u.s.ter bud spray is, however, highly effective, and in general it is advised that this method be followed. If, however, previous experience has shown serious losses from aphids, or if they are present in extremely large numbers, the extra application may be well worth while.--Ill. Agri. Exp. Station.

Although this was an off year for apples, results were probably as good here as in other sections of the state. The spring gave promise of an unusual crop, but the constant dropping of fruit during the summer months left us with about two-thirds as many apples as were harvested in 1914. The quality was much poorer, owing to extremely cool weather and the presence of scab in many localities.

The plum crop failed almost completely, and many trees were injured from aphis attacks. I have never known the aphis so hard to control as they were last summer.

Nearly all fruit trees made an excellent growth this season, and the new wood was well ripened when the freeze-up came. The fall rains provided plenty of moisture, and our trees should come through the winter in excellent shape.

Raspberries and currants produced about one-half the usual crop this year, probably owing to our May freeze.

Strawberries were almost a failure, largely due to winter-killing. Last winter did more damage to perennial plants than any other winter within the recollection of the writer. The fall was rather dry, and our snow covering did not come until January.

We received from Supt. Haralson for trial four plum trees, variety No.

1; and fifty everbearing strawberry plants, variety No. 1017. Both plum trees and strawberry plants made a good growth. Although the strawberries were set heavily with fruit, but little of it ripened before the heavy frosts came. The plant is very vigorous, and the berry is large and of excellent quality.

On May 18th we had several inches of snow accompanied by a fierce northwest wind, and orchards without any shelter suffered seriously, and both apples and plums in such orchards were scarce and of a rather inferior quality. A few orchards had a fair crop, while a couple of others with a natural windbreak had a fairly good crop, but on an average it was the lightest apple and plum crop we have had for some time.

Mr. Beiersdorf and Mr. Swichtenberg report a good crop of Wealthy and Peter. Their orchards are close to a lake and are well protected on the north and west by a natural grove.

Of the twenty-four report blanks sent out, eleven were returned properly filled in, and they all report conditions about as above outlined.

Cherries and grapes suffered even more from the cold than the apples, and that crop was very light. My Homer cherry trees look healthy and are growing fine, but the past two years had not enough fruit to supply the birds.

Raspberries and strawberries were a good crop and of exceptional fine quality, but the currants and gooseberries were a total failure in my garden as well as elsewhere, according to all reports received.

There were not many fruit trees planted in this district the past year.

For instance, at this station the deliveries last spring consisted princ.i.p.ally of bundles containing one-half dozen or a dozen trees each, and the total number delivered in that way did not exceed 200 trees and, according to all information, the planting throughout this district was very light.

I know of only one new orchard started with 700 four and five year old trees. About 500 are Wealthys and the balance Patten Greenings. The trees made a good start but were somewhat neglected during the summer, the field being planted to corn and some to barley, and all was handled rather rough.

There was very little blight in this district the past year. I noticed just a little on two or three Transcendents, and Mr. Jos. Boll, who has about 1,500 bearing trees, reports no blight at all.

I did no spraying this year, did not consider it worth while, as there was no fruit, and most others felt the same way. Other years though a lot of spraying is done, and the more progressive ones spray two and three times.

There is plenty of moisture in the soil, and the trees are going into winter quarters in good shape, therefore prospects for apple and plum crop the coming season are excellent.

[Ill.u.s.tration: Residence of M. H. Hegerle, St. Bonifacius.]

Probably a hundred or more different kinds of apple and plum trees and berries of all kinds are grown here. Farmers in the past usually bought what the salesman recommended, just to get rid of him; lately though they are taking more interest in the selection, and the Wealthy, Patten's or Northwestern Greenings, Okabena, Peter and perhaps a few d.u.c.h.ess are about the only apple trees planted now. Surprise plums, Dunlap and everbearing strawberries are the leaders.

Ornamental shrubs are found here of all names and descriptions and colors, and they all seem to do well.

HONEY VINEGAR.--Vinegar made from honey has an exceptionally fine flavor and is not expensive. A small amount of honey furnishes a large amount of vinegar. Follow these directions: Dissolve thoroughly in two gallons of warm, soft water one quart jar of extracted honey. Give it air and keep it in a warm place, where it will ferment and make excellent vinegar.--Missouri College of Agriculture.

Thirty Years in Raspberries.

GUST JOHNSON, RETIRED FRUIT GROWER, MINNEAPOLIS.

Of the growing of fruit, it may well be said, "Experience is a good teacher, but a dear school."

When I began fruit growing, some thirty years ago, I did not begin it merely as an experiment. I was interested in every branch of the work and, being very much in earnest about it, I felt confident of success.

Thinking that the failures and drawbacks sometimes experienced could be easily overcome by a thorough understanding of the work at hand, I began by getting all the information possible. I found that great books such as by Downing, Thomas, etc., were more suitable for the advanced fruit grower, but I studied all the pamphlets and books obtainable during the winter months and put this knowledge into practice during the summer. Of course I could not put into practice all I had obtained from this reading, but I remembered distinctly the advice to all amateur fruit growers to start out slowly. This was particularly suited to my case, for the land was covered with timber, some of which I grubbed each summer, gradually adding acres as I cleared the land.

My first venture was in planting raspberries, planting potatoes between the rows the first year. One delusion I had was in planting as many different and untested varieties as I could afford to buy and not confining myself to those that had been tried and had proven satisfactory. Fortunately for me, the high cost of plants at this time did not warrant my buying as many different varieties as I desired, and I had to be contented with fewer plants. From the most promising of these, I saved all the plants possible.

I had an idea that I could do better by sending to some of the Eastern states for my plants, but here again I was mistaken, for the plants often did not arrive until late in May, and by the time they had reached their destination were practically all dried out. The warm weather then coming on, I lost the greater part of them, although I had carefully hoed and tended them in the hope that they would finally revive. Here I might also mention that the express charges added considerably to the cost of these already expensive plants.

As a beginner I put much unnecessary labor on these plants. While I do not wish to leave the impression that hoeing and caring for them is not all right, still there should be a happy medium which I later learned as I became more experienced along this line. I must admit, however, that this rich, new land thus cultivated certainly yielded some wonderful fruit.

As time went by, I kept adding to my plantation, and owing to the large yield and the good demand for the black caps I took a fancy to raising them. When the Palmer variety was first introduced, I planted quite a field of them. I shall never forget the way these berries ripened, and such a lot of them as there were. Practically every one by this time having planted black caps, their great yield soon overstocked the market, and berries finally dropped as low as 65c or 70c a crate.

Having decided to dig up these black caps, I began paying closer attention to the red raspberry. I noticed that the raspberries growing wild on my place grew mostly in places where big trees had been cut down and young trees had grown up, thus partly shading the plants. Having this fact in mind, I planted the raspberries as follows: I planted an orchard, having the trees in parallel rows, and between the trees in these same rows I planted the raspberries. By planting in this manner, the cultivation would benefit the trees as well as the smaller plants.

Of course after the trees began bearing heavily, the plants nearest the trees had to be removed, and later the other plants likewise were removed.

As a beginner it was a puzzle to me which varieties I should plant. All varieties listed in the numerous catalogs were so highly recommended as being hardy, large yielders, good shippers, etc., that the selection of plants was not an easy matter.

The speed with which a new variety of raspberry is sent out over the country and discarded is surprising. The most popular sort at this time was the "Turner" variety. I did not, however, fancy this variety, for it suckered so immensely that it required continual hoeing to keep the new plants cut down. The berries were unusually soft and settled down in the boxes, which greatly detracted from their appearance in the crates.

There were also at this time a few of the "Philadelphia" variety being planted. They are a dark, soft variety and somewhat similar to the Turner.

Just at this time there was being sent out a new variety, known as the Cuthbert, or Queen of the Market, and queen it was indeed. This was a large, firm berry, and after ripening it would remain on the plant a long time without falling off. These plants grew up in remarkably long canes, but not knowing how to head them back they would often topple over during a heavy storm. This added another valuable lesson to my increasing experience, which resulted in my pinching of the new canes as soon as they had attained a height of from three to four feet. This made the plants more stocky and more able to support their load of berries without the aid of wire or stakes.
