amount of solids. In 230" cases the evidence and tests showed adul- 

 terations of original composition of milk by watering or skimming, 

 or both. One very remarkable statement is made by the Commis- 

 sioner: That but one case of added preservative (formaldehyde) was 

 found; whereas, eleven years ago there were found in the samples 

 of milk gatliered, GOO cases of formaldehyde preservative. 



There has been a marked increase in the number of oleomargarine 

 licenses issued for the year — in fact for nine years this yearly in- 

 crease has been going on. As an evidence of the successful operations 

 of the Bureau, nine years ago, in Philadelphia, there were but three 

 dealers who had license to sell oleomargarine; in 1915, there were 

 granted to Philadelphia alone, 300 licenses to sell same. This large 

 increase in the number of licenses was due to the vigilance of the 

 field agents in prosecuting dealers selling oleomargarine for butter. 

 Last year the activity of the agents in apprehending violators of the 

 pure food laws has been more marked than before; and because of 

 this activity, there has been an equally marked improvement in the 

 foods of State. 



During the year the chemists of the Department analyzed 8,939 

 samples of various food stuffs, in which were found the following 

 violations of the pure food laws and for which prosecutions w^ere 

 made: Milk, G25; coffee and chicory, 2; cold storage goods, 75; eggs, 

 17; miscellaneous foods, 175; ice cream, 8; non-alcoholic drinks, 76; 

 oleomargarine, 16; renovated butter, 2; sausage, 25 and vinegar, 

 101. 



I would call your Excellency's attention to two laws that should 

 be on the statute books of the Commonwealth to make complete the 

 laws of the Department in the carrying out of the purposes for 

 which the Bureau was established : A Sanitary Law which would 

 apply to creameries, cheese factories, condenseries, canneries or other 

 places where foods are manufactured for sale. The other measure 

 I would call to your attention, is a law prohibiting the sale of adul- 

 terated or misbranded alcoholic liquors. 



BUREAU OF ECONOMIC ZOOLOGY 



The report of the Economic Zoologist is published as a part of this 

 Annual Report, in which is given, in detail, the work of that Bureau. 

 The collection of insects, both beneficial and injurious, as classi- 

 fied, is considered equal to the best in the State, and are arranged 

 by the Entomologist so that they can be seen and studied, and many 

 take advantage of the o])portunity, especially school children. 



The field work of the Bureau has been carried on by the Orchard 

 Inspection Service, and it is worthy of note, that during the year the 

 first orchard inspection begun eight years ago was completed this 

 year. 



Orchard demonstrations were continued, there being held during 

 the year 262 public demonsfrations. Ten hundred and fifty-one 

 visits were made to individual orchards by the inspecting force.
