188 BOARD OF AGRICULTURE. [Pub. Doc. 



elects entomology is asked what business he intends to fol- 

 low after graduation, and he is then advised to prepare his 

 thesis on those insects with which he will most have to deal 

 in the business of life. In the preparation of this thesis the 

 work is carried on in the most approved method, so that he 

 may obtain the most thorough scientific and at the same time 

 practical knowledge of the subject ; in fact, he is taught 

 methods of investigation, so that, if new insect pests should 

 appear on his crops, he will know how to properly investi- 

 gate them and discover the best and cheapest methods for 

 their destruction. If this thesis proves to contain matters 

 of public interest, whether of an economic character or 

 otherwise, it is published with whatever illustrations are 

 necessary. 



Economic entomology is divided, for convenience, into 

 insects injurious in the greenhouse, in the garden, in the 

 orchard, in the field, in the forest, to domestic animals, 

 household pests, and the science and practice of bee-keeping. 

 Instruction is also given on insecticides and apparatus for 

 the application of insecticides. As the laboratory is in the 

 same building with the iusectary, all the members of the 

 class have the opportunity of frequently inspecting the vari- 

 ous experiments on different insects in this department of 

 the Hatch Station. 



This department is now prepared for and is receiving 

 graduates from this and other colleges who wish to continue 

 the study of entomology beyond what they were able in their 

 undergraduate courses. These advanced studies will fit them 

 for positions in the experiment stations or as State or gov- 

 ernment entomologists, and also give them most excellent 

 training as teachers in our high schools and colleges. 



Botanical Department. 

 The botanical museum contains a large collection of models 

 of fruit and specimens of all the woods found indigenous to 

 Massachusetts, and also the Knowlton Herbarium, the gift of 

 the late William Knowlton of Upton, numbering over ten 

 thousand specimens of plants from nearly all parts of the 

 world. Last winter the Legislature appropriated $1,200 for 

 an extension of the botanical laboratory. This extension
