第 12 頁 - SEC. 2. That it shall be the object and duty of said experiment stations to conduct original researches or verify experiments on the physiology of plants and animals; the diseases to which they are severally subject, with the remedies for the same; the chemical composition of useful plants at their different stages of growth; the comparative advantages of rotative cropping...
第 81 頁 - As to the general effect produced by grass on young apple trees, the results of the last few years have brought forward nothing which can in any way modify our previous conclusions as to the intensely deleterious nature of this effect, and we can only repeat that no ordinary form of ill-treatment — including even the combination of bad planting, growth of weeds and total neglect — is so harmful to the trees as growing grass round them.

第 81 頁 - The United States Department of Agriculture has published a number of observations and experiments to show that different plants growing in the same soil may poison each other. I am able to give also the results of a most excellent series of experiments planned and carried out on the Woburn Experimental Farm in England. These experiments were planned to show the effects of growing trees in grass, the latter to be used as a mulch. The following gives the gist of the results of the experiments in question...

The phosphate and potash combination has affected yield in this case rather decidedly, having raised it by 123 bushels per acre. This may be partly due to a slight superiority in location, as indicated by the fact that its adjacent check is the highest in yield and is within 88 bushels of the phosphate-potash treatment.
第 34 頁 - The origin, the first home of the plants most useful to man, and which have accompanied him from the remotest epochs, is a secret as impenetrable as the dwelling of all our domestic animals. . . . We do not know what region produced spontaneously wheat, barley, oats, and rye. The plants which constitute the natural riches of all the inhabitants of the tropics, the banana, the papaw, the manioc, and maize, have never been found in a wild state.
