Excerpt from Field and Laboratory Studies of Soils: An Elementary Manual for Students of Agriculture
A supply of clean sand, and also some loam, clay and muck soil should be secured in the fall. This material should be dried, pulverized, and passed through a sieve with one eighth-inch mesh, to remove stones and sticks.
The exercises are intended to furnish sufficient material for one period per week throughout the year or two periods per week for a half year. Although they are arranged in logical order, it is not necessary that the exercises should be taken up in the exact sequence in which they occur in the text. Indeed, it will be necessary for the teacher to vary the arrangement in order to adapt the study to the season and to the facilities of the school.
A small working library should form a part of the equipment. For a study of soils this library should include several elementary books on soils, a collection of Farmers' Bulletins from the United States Department of Agriculture and the publications of the State Experiment Station.
