Excerpt from The Preparation of Substances, Important in Agriculture: A Laboratory Manual of Synthetic Agricultural Chemistry Third Edition
It has been the aim in this manual to select substances of agricultural interest, adapt them to laboratory preparation, and explain their chemistry to the best of our present knowledge not overlooking their practical significance.
The work was at first nothing more than laboratory directions, but the interest of the student gradually required the addition of explanatory matter to such a degree that the emphasis on an accompanying text has been greatly reduced. The method of presentation aims to put a few major points before the student and extend the work on such points over so long a time that the student wall absorb it. The author feels that when a student, in his earlier years in college, works interestedly for a whole exercise around one thing he grasps something while if a dozen important points pass in review during the time he is left in a maze and gets little but technical benefit.
