SPECIAL STUDIES. 75 ology is laid by the discussion and detailed study of a typical insect; and for that of the orders, by a generalization of the characters of selected groups of specimens representing each. A large part of the time is devoted to the study of the characters, life histories, habits and economic relations of one hundred species of especially important insects. Specimens of these in their different stages, together with synopses and descriptions of the families to which they belong, are furnished the students, and the essential facts not discoverable by direct observation, are given in lectures or acquired by study of text. Practice in field observations is given as opportunity offers, and all are taught the ordinary methods of the collection, preparation and care of specimens, together with the approved methods of controlling the ravages of the injurious species. A careful and complete description of some one species, illustrated by drawings of important parts, is made by each student and deposited in the library of the school. Besides the collections, apparatus and entomological library of the University, the students in this course have access to the collections and library of the State Entomologist, and the practical use of the many thousand duplicate insects belonging to the office. In both field and laboratory work, an extraordinary opportunity is afforded competent students of this course to observe and assist in practical entomological work and original research. Mineralogy Fourteen weeks; about six weeks are occupied in lectures on crystallography; Nauman's system of symbols is used and explained. A collection of models, comprising the most important forms and combinations in the various systems of crystalization, is used for illustration and study. The remainder of the term is occupied by the descriptive determination of minerals, and the use of the blow pipe. A very complete collection of minerals, both American and foreign, has been furnished for this purpose. APPARATUS.
