Prof. Sanborn concludes from his experiments thus far that the surface gains moisture from soil beneath it by capillary action, but gathers nothing from the air. This is made strongly probable, if not shown; first, because the soil is warmer by night than the air. (He relies upon other facts than his own for this assertion.) 2nd. Because he found more moisture in the soil when covered over night than when left bare. 3d. Because when hoed, thereby disturbing capillary action, he found less moisture than when unhoed, in surface soil. Finally, he concludes the position proven, for, when he shut off the upward flow of water to the surface of the soil, he found not only less moisture above the cut off or in the surface soil than where no disturbance of capillary action had been made, but actually less moisture in the surface soil than the night before. Strongly corroborating this conclusion is the fact that all of the tests conspire to show that the gain of moisture in the surface of the soil by night is traceable to one source, and only one source. [Illustration: AMERICAN ASH.--See Page 25.] The facts of this bulletin accord with the previous ones in showing that mulching and frequent shallow tillage economize the moisture of the soil and add new proof of this to those already given. SPECIALTY IN FARMING. This subject in my estimation should begin to attract attention, especially among the large land owners and farmers of the West. If we study the whole catalogue of money-making enterprises and money-making men, we find that the greatest success has been attained where there has been the greatest concentration on a special line of work. True, it is, that specialists are subject to unexpected changes of the times, and if thrown out of their employment are not well prepared for other work, and yet their chances for success as compared with the "general idea" man are as ten to one. For an example look at science. How has it advanced? Is it not by the invaluable aid of men who have given their whole lives to the solution of some special problem? It could not be otherwise. If every scientist had attempted to master the majority of scientific truths before he was contented to concentrate his time on some special branch of science, science would have progressed little or none at all. Linnaeus opened the way in botany, and the world profited by his blunders. But to be brief--it seems to me that the most successful farmer in the future is to be the man who can so arrange his work that he is led into the deepest research on some one branch of farming. He must be a specialist. He must thoroughly master the raising of fine stock for breeding purposes, for practical profit and the shambles. Attend stock associations, and hear witnesses testify on every hand to the difficulties connected with properly rearing calves for breeding purposes.
