BUREAU OF ECONOMIC ZOOLOGY 



The work of this liiiieau was pursiied (lviriii<; ilic year with the 

 Iji'oinptiiess aud activity its character demands. Many accessions 

 were made to the luiniher of specimens sent to the lliirean by coi*- 

 resi)on(ients. with retjuests I'or inforniation re<4ardin<> I he same. One 

 h\indred aud eiglity-eight nurseries, covering over thiee thousand 

 acres of gnmnd, were inspected, and certificates of freedom from in- 

 lurions ])ests or diseases were issued to owners entitled to the sanu', 

 as recjuired by law. 



Twenty-six agents of the Bureau were engaged during almost the 

 entire j'ear in the insi)ection of private orchards and the demon- 

 stration of methods to )»e employed for the destruction of insect pests 

 and fungus and other diseases destructive to the fruit growing in- 

 dustry. More than a million trees were inspected and moie than two 

 thousand of the public demonstrations referred to were given dur- 

 ing the vear. 



Man}' inspections Avere made also of imported plants and seeds

FERTILIZER CONTROL 



During the year 1910, 1,482 brands of Commercial Fertilizer and 

 fertilizing substances were registered with the Department, upon 

 which 126,170.00 was paid and turned over to the State Treasury, 

 as required by law. 



Foirrteerr saiu])ling agents were employed for a period of eighi 

 weeks, four weeks being devoted to spring and four to fall sampling. 



Two thousand eight hundred and eighty-seven samples were se- 

 cured and one thousand one hundred and forty-four analyses were 

 made. In very many instances, sairrples of the same goods secured 

 in dilferent sections of the State were composited so as to reduce 

 to a minimum the number of analyses to be made, without detracting 

 from the efficiency of the work. 



Fifteen cases were terminated during the year, for violations of 

 the Fertilizer laAvs of the State, resulting in the payment of Four 

 Hundred Dollars in fines which were paid into the Treasury of the 

 Commonwealth. 



BUREAU OF CHEMISTRY 



The amount of work done by the Bureau of Chemistry during the 

 year 1910 exceeded that of the previous year. The collection of 

 samples of Feeding Stuffs, Paris Green and Linseed Oil, in compli- 

 ance with the laws regulating the sale of these commodities, was 

 carried on as in former years. 



During the year, 1,500 samples of Feeding Stuffs were received 

 and analyzed, and reports were made in each case to the Secretary 

 of Agriculture, to the dealers from whom they were obtained and 

 to the manufacturers or importers. The quality of Feeding Stutfs 

 examined was found to be considerable better than those secured last 

 year. The nirmber of deficiencies was less and the adulterants fouird 

 were not of such a fraudulent nature. No Feeding Stuffs were found 

 which contained peanut shucks or rice hulls. The principal forms of
