"No, Mr. White," replied Bob, "Aunt Bettie and I decided first on the size of the dairy herd. We thought that twenty cows would be as many as we would be able to take care of on a farm of the size of ours, if we do general farming. We have used a twenty-cow herd as the basis of our calculations. We found by reading the recommendations in the Government's bulletins, that in order to keep a dairy of good milk cows, it would be necessary to take care of five calves and five yearling heifers, and an old and a young bull in order to keep the herd up to maximum production. We figure that a herd of twenty Holstein cows ought to average two hundred quarts of milk daily. This would mean ten twenty-quart cans to take care of the milk, and, allowing for the ice, would require a trough nine feet by two feet six inches by two feet. If we separate the cream, of course, it wouldn't require such a large trough. But we used this as a basis of the dairy requirements. Then we found by looking up another Government bulletin that it would take about twenty tons of ice to take care of this milk, but we need ice around the farm for other things, too, so we decided to make the icehouse large enough for thirty tons. Aunt Bettie and I read all the bulletins we could get from the Government and then we looked up the different ones sent out by the Portland cement manufacturers, but we found they didn't exactly agree; besides, we felt that if we could build the icehouse inside of the dairy, the ice wouldn't melt so fast, so we've decided to make a combination building like this," he said, as he laid his plans before the banker. "We're going to put this building back of the woodshed where it will join the new cow barn." "But isn't a twenty-cow herd pretty large for one man to handle, Bob?" asked the banker. "No, Mr. White, you can get a two-unit milking machine now that will milk twenty to twenty-five cows in one hour and give a ninety-eight per cent. efficiency." "How much will that cost, Bob?" "We can get a complete two-unit outfit consisting of pump, air tanks, two milking units, installed in the barn, complete for $450." "But you've only ten cows, now, Bob. Wouldn't that be too large for them?" [Illustration: THE ELECTRIC MILKER SOON PAYS FOR ITSELF] [Illustration: COMFORTABLE SANITARY STALLS OF CONCRETE WITH WOOD BLOCKPAVING ON FLOOR. RUNNING WATER AND PLENTY OF SUNSHINE ASSURE A HEALTHY AND CONTENTED HERD] "No, Mr. White, the outfit is designed for from ten to twenty-five cows, and will do the milking twice as fast as by hand." "That's right, Bob; put in machinery and cut down help. Let's see, that would save at least two hours a day for one man at, say thirty cents an hour, or $219 per year. You say the complete outfit costs $450, which amount at six per cent, interest would mean $27, or a saving of $192. Quite a saving, Bob." "Have you laid out a general scheme for all your buildings?" asked the banker, much interested.
