Excerpt from Catechism of Agricultural Chemistry and Geology In introducing this little work to the notice of the American public, Iam encouraged by the hope that a conviction as to the importance of the new know ledge of which it treats, already fixed in many minds, will soon become universal. Agriculture, the art in whichtnine-tenths of the capital of civil ised nations is embarked, upon which all depend for subsistence, is rising towardsits proper rank as a science. We look forward to the time when it will be generally conducted upon fixed and scienti fic principles, dependent. Upon immutable laws. Obstacles may retard, but cannot permanently at rest its progress, and those who receive the light that we now possess, and keep pace with our in creasing knowledge, willrsurely reap the benefit which always results from the application of eu lightened. Skill; while those who linger behind must be content to grape on in blind uncertainty, as our forefathers have done.
