210 ANNUAL REPORT OF THE Off. Doc. 



samples, registration for feeds containing it were refused. The pro- 

 ducts was put out under the name of ''Vegetable Meal," which is 

 especially prepared, sterilized and dried garbage tankage. The 

 Bureau deemed it improper for this by-product to be used as an 

 ingredient in mixed feeds for the reason that it contained small 

 particles of glass which were, no doubt, introduced into the garbage 

 by broken glassware. The propriety of permitting this material to 

 be used as a feeding stuffs is now being considered by the various 

 State officials. The company manufacturing thisi product have 

 stated to the Association that the method of manufacturing has not 

 been fully perfected, as an attempt is being made to entirely elimin- 

 ate any particles of glass or other foreign materials and remove all 

 objectionable features. If this so called ''Vegetable Meal" can be 

 sold under a name properly describing it and all foreign particles 

 can be removed, it will, no doubt, be of considerable value as an 

 ingredient in feeding stuffs. 



The general character of the feeding stuffs sold in the State dur- 

 ing 1915, as judged from the samples examined, was good. Con- 

 siderable improvement has been made with respect to labeling, meet- 

 ing the guarantees and keeping out the weed seeds from chicken 

 feeds. There is still room, however, for improvement in this re- 

 spect and as the work progresses from year to year the objectionable 

 features referred to will, no doubt, be largely overcome. The usual 

 number of registrations were received and filed representing over 

 1,600 kinds and brands of feeds. In December requests for 1916 

 registrations were sent out with a ruling to the effect that the De- 

 partment deemed it contrary to the provisions of the feeding stuffs 

 law to use the so-called "sliding guarantees" for protein, fat and 

 fiber. For a number of years this method of guaranteeing has been 

 in vogue and the results of inspection work made by this Bureau 

 show that in the majority of cases the maximum guarantees are not 

 met and in many cases the lower guarantees were frequently too 

 high. Such guarantees, therefore, are misleading and it is hoped 

 that this ruling will be complied with during the coming year. When 

 making requests for the 1915 registrations an attempt was made to 

 determine the approximate number of tons of feeding stuffs sold in 

 the State during 1914. Accordingly requests for this information 

 were sent out with registration blanks to which a majority of the 

 firms replied giving the approximate number of tons shipped or sold 

 by these firms. After these figures had been received they were 

 tabulated and returned to the firms sending them in. It is believed 

 that the total number of tons sold in Pennsylvania, according to these 

 figures, was entirely too low, however, as a number of the large firms 

 refused to give us the information, the correct figures could not be 

 ascertained. According to the reports received over 600,000 tons 

 of all classes of feeding stuffs were sold in the State during 1914. 

 These figures are interesting as they show the enormous quantities 

 of feeds being disposed of in the Commonwealth ; and it also indicates 

 the need of the enforcement of a feeding stuffs law to make sure that 

 all these feeds are properly labeled and sold in accordance with the 

 requirements. The figures received are as follows: 



Cottonseed meal, 22,423 tons; linseed oil meal, 9,277 tons; dis- 

 tillers' dried grains, 7,627 tons; brewers' dried grains, 8,925 tons; 

 malt sprouts, 1,547 tons; corn gluten feed, 48,427 tons; corn gluten
