"You deceive yourself. It is not scientifically built, to begin, and there is a cause at work that will infallibly burst it, if not looked to in time."

"And what is that, sir?"

"The dam is full of crabs."

"So 'tis; but what of them?"

"I detected two of them that had perforated the d.y.k.e from the wet side to the dry, and water was trickling through the channel they had made.

Now, for me to catch two that had come right through, there must be a great many at work honeycombing your d.y.k.e; those channels, once made, will be enlarged by the permeating water, and a mere cupful of water forced into a d.y.k.e by the great pressure of a heavy column has an expansive power quite out of proportion to the quant.i.ty forced in.

Colossal d.y.k.es have been burst in this way with disastrous effects.

Indeed, it is only a question of time, and I would not guarantee your d.y.k.e twelve hours. It is full, too, with the heavy rains."

"Here's a go!" said d.i.c.k, turning pale. "Well, if it is to burst, it must."

"Why so? You can make it safe in a few hours. You have got a clumsy contrivance for letting off the excess of water: let us go and relieve the dam at once of two feet of water. That will make it safe for a day or two, and to-morrow we will puddle it afresh, and demolish those busy excavators."

He spoke with such authority and earnestness, that they all got up from table; a horn was blown that soon brought the Hottentots, and they all proceeded to the dam. With infinite difficulty they opened the waste sluice, lowered the water two feet, and so drenched the arid soil that in forty-eight hours flowers unknown sprang up.

Next morning, under the doctor's orders, all the black men and boys were diving with lumps of stiff clay and puddling the endangered wall with a thick wall of it. This took all the people the whole day.

Next day the clay wall was carried two feet higher, and then the doctor made them work on the other side and b.u.t.tress the d.y.k.e with supports so enormous as seemed extravagant to d.i.c.k and Phoebe; but, after all, it was as well to be on the safe side, they thought: and soon they were sure of it, for the whole work was hardly finished when the news came in that the d.y.k.e of a neighboring Boer, ten miles off, had exploded like a cannon, and emptied itself in five minutes, drowning the farm-yard and floating the furniture, but leaving them all to perish of drought; and indeed the Boer's cart came every day, with empty barrels, for some time, to beg water of the Dales. Ucatella pondered all this, and said her doctor child was wise.

This brief excitement over, Staines went back to his own gloomy thoughts, and they scarcely saw him, except at supper-time.

One evening he surprised them all by asking if they would add to all their kindness by lending him a horse, and a spade, and a few pounds to go to the diamond fields.

d.i.c.k Dale looked at his sister. She said, "We had rather lend them you to go home with, sir, if you must leave us; but, dear heart, I was half in hopes--d.i.c.k and I were talking it over only yesterday--that you would go partners like with us; ever since you saved the dam."

"I have too little to offer for that, Mrs. Falcon; and, besides, I am driven into a corner. I must make money quickly, or not at all: the diamonds are only three hundred miles off: for heaven's sake, let me try my luck."

They tried to dissuade him, and told him not one in fifty did any good at it.

"Ay, but I shall," said he. "Great bad luck is followed by great good luck, and I feel my turn is come. Not that I rely on luck. An accident directed my attention to the diamond a few years ago, and I read a number of prime works upon the subject that told me of things not known to the miners. It is clear, from the Cape journals, that they are looking for diamonds in the river only. Now, I am sure that is a mistake. Diamonds, like gold, have their matrix, and it is comparatively few gems that get washed into the river. I am confident that I shall find the volcanic matrix, and perhaps make my fortune in a week or two."

When the dialogue took this turn, Reginald Falcon's cheek began to flush, and his eyes to glitter.

Christopher continued: "You who have befriended me so will not turn back, I am sure, when I have such a chance before me; and as for the small sum of money I shall require, I will repay you some day, even if"--

"La, sir, don't talk so. If you put it that way, why, the best horse we have, and fifty pounds in good English gold, they are at your service to-morrow."

"And pick and spade to boot," said d.i.c.k, "and a double rifle, for there are lions, and Lord knows what, between this and the Vaal river."

"G.o.d bless you both!" said Christopher. "I will start to-morrow."

"And I'll go with you," said Reginald Falcon.

CHAPTER XX.

"Heaven forbid!" said Phoebe. "No, my dear, no more diamonds for us. We never had but one, and it brought us trouble."

"Nonsense, Phoebe," replied Falcon; "it was not the diamond's fault.

You know I have often wanted to go there, but you objected. You said you were afraid some evil would befall me. But now Solomon himself is going to the mines, let us have no more of that nonsense. We will take our rifles and our pistols."

"There--there--rifles and pistols," cried Phoebe; "that shows."

"And we will be there in a week; stay a month, and home with our pockets full of diamonds."

"And find me dead of a broken heart."

"Broken fiddlestick! We have been parted longer than that, and yet here we are all right."

"Ay, but the pitcher that goes too often to the well gets broke at last.

No, Reginald, now I have tasted three years' happiness and peace of mind, I cannot go through what I used in England. Oh, doctor! have you the heart to part man and wife, that have never been a day from each other all these years?"

"Mrs. Falcon, I would not do it for all the diamonds in Brazil. No, Mr.

Falcon, I need hardly say how charmed I should be to have your company: but that is a pleasure I shall certainly deny myself, after what your good wife has said. I owe her too much to cause her a single pang."

"Doctor," said the charming Reginald, "you are a gentleman and side with the lady. Quite right. It adds to my esteem, if possible. Make your mind easy; I will go alone. I am not a farmer. I am dead sick of this monotonous life; and, since I am compelled to speak my mind, a little ashamed, as a gentleman, of living on my wife and her brother, and doing nothing for myself. So I shall go to the Vaal river, and see a little life; here there's nothing but vegetation--and not much of that. Not a word more, Phoebe, if you please. I am a good, easy, affectionate husband, but I am a man, and not a child to be tied to a woman's ap.r.o.n-strings, however much I may love and respect her."

d.i.c.k put in his word: "Since you are so independent, you can WALK to the Vaal river. I can't spare a couple of horses."

This. .h.i.t the sybarite hard, and he cast a bitter glance of hatred at his brother-in-law, and fell into a moody silence.

But when he got Phoebe to himself, he descanted on her selfishness, d.i.c.k's rudeness, and his own wounded dignity, till he made her quite anxious he should have his own way. She came to Staines, with red eyes, and said, "Tell me, doctor, will there be any women up there--to take care of you?"

"Not a petticoat in the place, I believe. It is a very rough life; and how Falcon could think of leaving you and sweet little Tommy, and this life of health, and peace, and comfort--"

"Yet YOU do leave us, sir."

"I am the most unfortunate man upon the earth; Falcon is one of the happiest. Would I leave wife and child to go there? Ah me! I am dead to those I love. This is my one chance of seeing my darling again for many a long year perhaps. Oh, I must not speak of HER--it unmans me. My good, kind friend, I'll tell you what to do. When we are all at supper, let a horse be saddled and left in the yard for me. I'll bid you all good-night, and I'll put fifty miles between us before morning. Even then HE need not be told I am gone; he will not follow me."

"You are very good, sir," said Phoebe; "but no. Too much has been said. I can't have him humbled by my brother, nor any one. He says I am selfish. Perhaps I am; though I never was called so. I can't bear he should think me selfish. He WILL go, and so let us have no ill blood about it. Since he is to go, of course I'd much liever he should go with you than by himself. You are sure there are no women up there--to take care of--you--both? You must be purse-bearer, sir, and look to every penny. He is too generous when he has got money to spend."

In short, Reginald had played so upon her heart, that she now urged the joint expedition, only she asked a delay of a day or two to equip them, and steel herself to the separation.

Staines did not share those vague fears that overpowered the wife, whose bitter experiences were unknown to him; but he felt uncomfortable at her condition--for now she was often in tears--and he said all he could to comfort her; and he also advised her how to profit by these terrible diamonds, in her way. He pointed out to her that her farm lay right in the road to the diamonds, yet the traffic all shunned her, pa.s.sing twenty miles to the westward. Said he, "You should profit by all your resources. You have wood, a great rarity in Africa; order a portable forge; run up a building where miners can sleep, another where they can feed; the grain you have so wisely refused to sell, grind it into flour."

"Dear heart! why, there's neither wind nor water to turn a mill."

"But there are oxen. I'll show you how to make an ox-mill. Send your Cape cart into Cape Town for iron lathes, for coffee and tea, and groceries by the hundredweight. The moment you are ready--for success depends on the order in which we act--then prepare great boards, and plant them twenty miles south. Write or paint on them, very large, 'The nearest way to the Diamond Mines, through Dale's Kloof, where is excellent accommodation for man and beast. Tea, coffee, home-made bread, fresh b.u.t.ter, etc., etc.' Do this, and you will soon leave off decrying diamonds. This is the sure way to coin them. I myself take the doubtful way; but I can't help it. I am a dead man, and swift good fortune will give me life. You can afford to go the slower road and the surer."

Then he drew her a model of an ox-mill, and of a miner's dormitory, the part.i.tions six feet six apart, so that these very part.i.tions formed the bedstead, the bed-sacking being hooked to the uprights. He drew his model for twenty bedrooms.

The portable forge and the ox-mill pleased d.i.c.k Dale most, but the part.i.tioned bedsteads charmed Phoebe. She said, "Oh, doctor, how can one man's head hold so many things? If there's a man on earth I can trust my husband with, 'tis you. But if things go cross up there, promise me you will come back at once and cast in your lot with us. We have got money and stock, and you have got headpiece; we might do very well together.

Indeed, indeed we might. Promise me. Oh, do, please, promise me!"
