ENTOMOLOGICAL LABOEATOET. 



The equipment for work in entomology during the senior year 

 and for graduate students is unusually good. The laboratory building 

 contains a large room for laboratory work, provided with tables, dis- 

 secting and compound microscopes, microtomes, reaeents and glass- 

 ware, and one portion is fitted up as a lecture room. Another room 

 is devoted to library purposes, and contains a card catalogue of over 

 forty thousand cards devoted to the literature of insects. In addition 

 to a well selected list of entomological works in this room, the college 

 library has an unusual number of rare and valuable books on this 

 subject, and this is supplemented by the library of Amherst College 

 and by the private entomological library of the professor in charge, 

 which contains over 2500 volumes, many of which cannot be found 

 elsewhere in the United States. In another room in the laboratory is 

 a large and growing collection of insects, both adult and in the early 

 stages, which is of much assistance to the students. The laboratory 

 being directly connected with the insectary of the Hatch Experiment 

 Station, the facilities of the latter are directly available. The appa- 

 ratus room of the insectary, with its samples of spray pumps, nozzles 

 and other articles for the practical treatment of insects; the chemical 

 room, fitted up for the analysis of insecticides and other chemico-
