ANNUAL REPORT OF THE) DIVISION OF 



ZOOLOGY. 



To the Hon. N. B. Critchfield, Secretary of Agriculture; 



Dear Sir: I have the honor to submit the following report of the 

 Division of Zoology of the Department of Agriculture for the cal- 

 endar year 1903. 



On March 30, 1903, the present Economic Zoologist was appointed 

 by Governor Pennypacker, and it is our present duty to render a 

 report of the work of this office for the year now closing. To fully 

 understand this, one should know the conditions confronting the 

 incumbent. When he entered the office, the lack of equipment was 

 especially remarkable. There was no collection of specimens for 

 study or for comparison, almost no reference literature, very few 

 of the publications of the United States Department of Agriculture 

 or of the Bulletins of the various State Experiment Stations of the 

 United States, no mailing list, no facilities for mailing, no mailing 

 machine, no collecting material, no spraying apparatus nor facili- 

 ties for experimentation, no cabinet nor accessories for preserving 

 insects or other specimens, no room for the proper kind of work, no 

 office boy, scientific assistant, field assistant, nor stenographer. 



B}' 3'our kind aid, Mr. Secretarj-, and that of the Governor, and 

 the Board of Public Grounds and Buildings, most of the minor 

 deficiencies have been met, and the most urgent needs of the Divi- 

 sion have been supplied. 



I beg to submit the present report under the following sub-heads:
