Liebig said, Agriculture is, of all industrial pursuits, the rich est ih facts and the poorest in their comprehension. To a large degree this statement is still true, and the chief purpose of this volume is to bring together in convenient form the world's most essential facts gathered from the field and laboratory, and to develop from them some foundation principles of permanent agriculture; for, as Liebig also truly said, Facts are like grains of sand which are moved by the wind, but principles are these same grains cemented into rocks. While one dare not believe that error has been completely av'oided, the facts presented have been checked with all reasonable care, and they may be accepted with the confidence that they are accurately reproduced from the original data.
