begun, Tliroiigh the agency of the station a modification of the 

 fire laws has been secured. 



In cooperation with the Bureau of Plant Industry of this depart- 

 ment, studios on tobacco are in progress near Hartford, in which 

 the effect of large amounts of phosphate in tobacco fertilizers and a 

 comparison of the method of harvesting broad-leaf tobacco by pick- 

 ing or priming by the usual method of harvesting the whole plant are 

 receiving attention. This work has demonstrated the desirability 

 of certain changes in tobacco fertilizers, and the value of steam 

 sterilization of tobacco beds which destroys fungus diseases and 

 makes weeding of the beds unnecessary. 



The plant pathologist pursued numerous lines of work, including 

 investigations on peach yellows, sun scald of trees, blight of Lima 

 beans, potato blight, tobacco diseases, etc. The experiments on the 

 calico or mosaic disease of tobacco indicated the extremely infectious 

 nature of the malady and its being an enzymatic disturbance. An 

 experiment on a plat of 900 peach trees was made to determine the 

 relation of fertilizers to peach yellows. A large number of spraying 

 experiments were conducted to find the most efficient methods for 

 the control of plant diseases and the specific action of Bordeaux 

 mixture. Field work w^as carried on with cowpeas and alfalfa to 

 test the value of artificial inoculation. Some plant-breeding work 

 was clone, principally with hybrid varieties of corn and for diseaise 

 resistance in melons, cucumbers, etc. A report of tests of summer 

 sprays on apples and peaches, conducted by the botanist and the 

 entomologist, was issued during the year. 



The entomologist gave much attention to gipsy-moth control, and 

 reported the practical extermination of this pest at Stoningion and 

 the control of the infested area at Wallingford. Cooperative work 

 was carried on with the Bureau of Entomology of this department 

 on the foreign importation of gipsy-moth parasites. The last legis- 

 lature provided for a bee inspection and assigned the work to the 

 entomologist of the station. 



The chemical department, in addition to its extensive inspection 

 work, carried on studies of the various ammoniates in fertilizers in 

 field and in pot cultures. The control work of the station, in addition 

 to the bee inspection mentioned above, includes nursery inspection, 

 the analysis of fertilizers, feeds, food products, and drugs, and the 

 testing of seeds. 



The station took an active part in the various agi-icultural fairs 

 of the State, exhibiting its work in a large tent. The exhibits and 

 lectures attracted a great deal of attention. No other extension work 

 was undertaken by the station. 



The following publications were received from this station during 

 the year : Bulletins 104, Garden and Field Seeds Sold in Connecticut
