Excerpt from Hints on Soils and Fertilizers We have already learned that the soil con tains mainly two classes of materials, humus and mineral elements. We have defined humus as decayed vegetable matter, such as the re mains of plants that were not used by man, but left upon the soil. The elements of a mineral nature are just as essential to the welfare of the plant as the Organic matter, or humus. We will discuss these mineral ele ments from a chemical point of view in our next chapter, but we will now consider them briefly from a phy'sical standpoint.

Excerpt from Soils and Fertilizers It is evident from the preceding example that any thing like an adequate idea of the growth and compo sitiou of plant bodies could not be gained until the composition of air and water was established. The discovery of oxygen by Priestley in 1774, of the composition of water by Cavendish in 1781, and of the r61e which carbon dioxide plays in plant and animal life by De Saussure and others in 1800, formed the nucleus of our present knowledge regarding the sources of matter stored up in plants. It was between 1760 and 1800 that alchemy lost its grip because of advances in knowledge and the way was opened for the development of modern chemistry.

Excerpt from Soils and Fertilizers, for Public Schools: A Discussion Upon the Nature and Treatment of Soils and the Value of Fertilizers There has been much ob eet'ion to the teaching of Agriculture in our District Schools, because teachers claim they do not have time to take up an additional subject, when they have so many subjects that are already required, and which must be taught. However, in recent years Agriculture has been coming into its own, and is being taught more and more in the schools. Teachers have begun to realize that any subject which holds the interest and attention of the pupils is worthwhile, and that any sub ect which does not hold their attention is not worthy of a place in our already crowded School course. In order to make Agriculture interesting to the pupil, we must base the work upon real practical problems which he can understand and appreciate. To do this is no small task, and it is a thing which demands a great deal of perseverance and initiative, on the part of teachers In such schools. The more ideas which an author attempts to incorporate into a text book, the more complex his text becomes, and the more difficult it is to follow. Therefore, in this text book we have taken' only a few of the most important conditions and have tried to incorporate them in such a manner that they can be used by the average district or graded school. We have tried further to make the book correct - theoretically and practically. The entire text has been written for boys and girls of the country schools, with these two things in mind, and the success which attends its use presupposes a proper presentation of many minor details, which it would be impossible to include under this cover. Many teachers get the idea that the sub ect of Agriculture as taught in our public schools is a Vocational Sub ect. This is' a mistaken idea, and the teachers should above all bear in mind that we are not making better farmers so much as we are making better men and women who are farmers. Naturally the teaching of Agriculture will make better farmers, and will serve to keep more of our boys on the farm.

Excerpt from Soils, How to Handle and Improve Them Many of the early books on farming were written in a technical style. They smacked of the lecture room and the library rather than of the soil. They were scholarly rather than practical. A spirit of directness and simplicity is beginning to dominate agricultural literature. The modern type of farm books is born of actual contact with the soil and a desire to be of service to the men who are getting a living from the soil. They are democratic; they discuss common things in a plain way. The long and tedious tables of figures in the old books are giving place to crisp summaries. The technical lecture-room phrases are replaced by words in common use on farms. The idea is not to present less science - for nothing is so practical as sound science - but to present science in a simple and practical way. This new spirit is contemporaneous with the farmers' institute, the farmer's reading-course, Nature-study, elementary agriculture in the public schools and other efforts to serve the man who tills the soil. It is an expression of a general movement which aims to democracise agricultural teaching. This book is an attempt to set forth the important facts about the soil in a plain and untechnical manner. It is not a contribution to agricultural science, but an interpretation of it - a new presentation of what is already known.
