440 ANNUAL, REPORT OF THE Off. Doc. 



Finally, parasitic insects must have more attention than they 

 have been given. Efforts have been made to introduce the Preying 

 Mantis into different parts of this State in order that it can result 

 in good by feeding upon insect pests, as it is now doing in the vicin- 

 ity of Philadelphia, where it has been accidentally but successfully 

 introduced, and is rapidly multiplying. The Lady Beetles deserve 

 attention, and should be studied, preserved and propagated, and if 

 this can be made practical they should be disseminated to infested 

 plants over the State. The same can be said of the thousands of 

 species of internal parasites which are really the chief factors in 

 keeping insect pests in control. Unfortunately, scientists know but 

 little of the real life habits of jjarasitic insects, and the practical 

 agriculturist knows less. It is a subject of which we should 

 know more, and which should be put upon a practical basis. 



In conclusion, let us all co-operate in these important lines of study 

 by sending specimens of insects and reports of incipient insect out- 

 breaks to the State Experiment Station and the State Department of 

 Agriculture, and receive the aid which the State can give from these 

 various sources. More education and advancement is needed in 

 tins line, as well as in many others, and we hope to see it pushed 

 successfully for those who need help. 



The CHAIRMAN: What action will be taken on this report, or 

 have you an}' questions? 



On motion, duly seconded, it was agreed to receive the report and 

 place it on file. 



The CHAIRMAN: Prof. Menges is also to report on this subject. 

 We are ready to listen to him. 



PROF. MENGES: I have no report to make; I believe Prof. Sur- 

 face's paper about covers the question, and as you are pressed for 

 time, I will ask to be excused. 



The CHAIRMAN: While we should be glad to hear from Prof. 

 Menges, I suppose we will have to comply with his request, and 

 excuse him. We will, therefore, proceed with the next number on 

 the program, the Report of Committee on Dairy and Dairy Products 

 bv R. J. Weld. 



This report is as follows: 



REPORT OF COMMITTEE ON 'DAIRYING AND DAIRY 



PRODUCTS. 



By Mr. R. J. Wbld, Chairman. 



At our last annual meeting, Prof. Thos. Shaw stated "that there 

 existed a direct relation between the amount of live stock kept on 

 the farms of the country and a profit that may be derived from those 

 farms." By reason of its geographical position, its large consuming 

 population and its nearness to the great seaboard markets, Pennsyl- 

 vania is peculiarly situated with reference to one branch of live
