GEHRS, B. S., M. S. ASSOCIATE PROFESSOR OF AGRICULTURE OF THE VVARRENSBURG STATE NORMAL, WARRENSBURG, MO. JOINT AUTHOR GEHRS AND JAMES ONE HUNDRED EXERCISES IN AGRICULTURE gorfe THE MACMILLAN COMPANY 1925 All rights reserved COPYRIGHT, 1917, BY THE MACMILLAN COMPANY. Set up and electrotyped. Published May, NorfoootJ Ipre0 J. S. Gushing Co. Berwick Smith Co. Norwood, Mass., U. S. A. PREFACE THIS book is the outgrowth of the authors feeling thatfthere is a nejjd and a demand for a book that will standardize seventm and ei thtarade agriculture. It is the authors belief that children in the seventh and eighth grades in the rural schools are as well if not better prepared to do superior work in agriculture than are freshmen in many of our town schools. The town pupil knows little about agriculture. The experience of the country boy or girl is rich in the practical affairs of agriculture. The Table of Contents indicates that the subject matter treated in this book fits closely the agricultural interests of the North Central States. The arrangement of the chapters follows as closely as possible the farmers seasonal occupational But since the seasonal sequence varies, the chapters may be studied in any order desired. The topics treated cover the demands of the courses of study in general use. Such topics as the origin, history, and importance of farm crops and animals are about agriculture but such topics as how to produce larger yields, use of more prolific varieties, the use of high-grade or pure-bred stock, how to feed well and economically, how to improve the soil, how to combat enemies, and how to choose, plan, and manage a farm, are topics that deal withmak ing our agriculture more productive. This is not primarily a book ABOUT agriculture but one ON Productive Agriculture. Contrary to the popular opinion, our crop yields per acre in the United States are not decreasing, but increasing. This is VI PREFACE shown in the following table based upon the United States Year books of Agriculture INCREASE IN YIELD IN FARM CROPS OF THE UNITED STATES Average Yield per Acre Barley Corn Wheat Oats Rye The average acreage yields of the leading crops of the United States for the period 1906-1915 have been greater than for any other equal period in American agriculture. Unless this book helps to increase the acreage yields, improve stock, make for better and more fruit, and promote better farm management, it will have failed of the purpose for which it has been written. Since the Extension Departments of the Agricultural Colleges are devoting so much time to organizing and directing club and home project work, this topic is wholly omitted from the dis cussions. Some club work can be done with profit. For infor mation regarding the organizing of clubs, write the Extension Department of your State Agricultural College. These Exten sion workers are specialists, and can give the best information obtainable on club work. Laboratory Exercises are provided at the close of each chap ter. These exercises illustrate and make clearer the principles brought out in the text. They can be done with a small amount of equipment, and will help to make the work in agriculture PREFACE vii more concrete, Laboratory work makes the subject more interesting, educative, and practical. A small amount of suggested correlation with other subjects, especially language andarithmetic, is found in the Laboratory Exercises. When other subjects are correlated with agriculture, agriculture should be the basis for correlation. Correlation in which nine-tenths of the time is devoted to subjects other than agriculture destroys the vital influence that agriculture should have in every rural community. The limitations due to the size of this volume, and the time of the pupils, compel the omission of many subjects that would be interesting and profitable... PRODUCTIVE AGRICULTURE BY JOHN H.
