114 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



A report of the receipts and expenditures for the United States 

 funds has been rendered in accordance with the schedules pre- 

 scribed by this department and has been approved. 



The work of the Storrs station is steadily prosecuted along several 



important lines, and the results secured are proving valuable to 



agriculture in general as well as to the agricultural industries of 



the State.

No important changes in this station took place during the year. 

 The farm purchased by the State a few years ago is entirely under 

 the control of the station, practically all of it being employed either 

 for experimental purposes or for supplying feed for the work stock. 

 The State appropriated $10,000 for farm buildings, with which a 

 new barn was recently completed, a new silo erected, and the old 

 barn reconstructed. 



Considerable progress was made on some of the projects supported 

 by the Adams fund. The work relating to the functions of tannin 

 in plants was practically completed. This investigation has brought 

 out the inhibitory effect of tannin on the germination and growth of 

 spores of man}^ species of fungi. The results seem to indicate 

 further that the action of tannin is complicated by the presence of 

 enzyms in plants. 



The horticultural department continued its work on the functions 

 of nitrogen, phosphoric acid, and potash in the growth of apple and 

 peach trees. Leaves were collected for analysis and measurements of 

 growth were made. It is believed that some differences, due to the 

 kind and amount of fertilizer apj^lied, can be noticed with peaches, 

 while with apples no results have thus far become apparent. The 

 study of the effect of the different fertilizers on bud production of 

 peaches is to be taken up. 



The veterinarian did no further work on glanders and concluded 

 his investigations on anthrax, the results of which are regarded as 

 showing the possibility of bringing about passive immunity through 

 inoculation with serum. It is claimed that an immunizing serum 

 producing immediate immunity from anthrax, which can be used in 

 controlling the disease in cases of outbreaks, and a single vaccine of 

 practical value and reducing the time in gaining immunity by one- 

 half, have been secured as a result of this work. A bulletin giving 

 the results in detail was prepared. Experiments on in-and-in breed- 

 ing with dairy cattle was begun by the station during the year, and a 

 study of the effect of variations in physical characters and chemical
