A special laboratory is devoted to investigations and instruction in the physics and chemistry of soils.

The Laboratory of Agricultural Chemistry is devoted primarily to the prosecution of chemical researches in relation to general agriculture, such as the chemical examination of waters, foods, agricultural products, etc., and the determination of technical questions relating to agricultural processes or manufactures. The results of this work are reported to the

persons interested; so far as they are of general interest they are published currently in the form of bulletins. Laboratory instruction has been provided by desk room in the laboratories for twenty-five advanced students (i.e., those who have taken silicate analysis in the chemistry department) and for special students for work in agricultural analysis.

The Fertilizer Control Laboratory, for the analysis of commercial fertilizers, established by act of the Legislature, occupies a new building planned and constructed especially for its use.

The Cereal Laboratory is equipped for work entrusted to the Experiment Station by the Governor of California under the law of 1905, and is associated with field work at cereal stations in different parts of the State. The laboratory operations consist of selection and analysis of cereals, and analysis of soils and fertilizers used in their production; also baking tests to determine commercial value and suitability of the flours secured from the varieties included in field and milling experiments.

Sugar-House Practice is maintained by facilities for practical instruction in sugar-house control, in which the student receives practice in the analysis of sugar-house products.
