148 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



The slieop breedinir project was thoroughly organized and an ar- 

 rangement made for cooperation with the Carnegie Institution, Sta- 

 tion for Experimental Evolution. 



The botanist practically completed his project on the fruit spot of 

 apples. The disease was definitely shown to be due to a fungus 

 which was studied, and methods of control by spraying were demon- 

 strated. 



Results are also reported from the activities of the station sup- 

 ported by the Hatch fund. The horticultural department made con- 

 siderable progress in work on varieties of lettuce, with strawberries 

 on the correlation of leaf and stem characteristics w^ith character- 

 istics of the fruit, carnation breeding, and some vegetables. In a 

 new plum orchard varieties and commercial possibilities of plum 

 culture are being tested. 



The agronomist continued work in corn breeding and tested field 

 and ensilage corn and small grains; the fertilizer work on the grass 

 plats was also continued. Cooperative tests of alfalfa carried on 

 with farmers gave some indications that this crop may be success- 

 fully grown under favorable conditions. Considerable attention was 

 given to the testing of seeds for purity. A pure-seed law was passed 

 by the legislature and placed in charge of the state board of agri- 

 culture for execution. The tests for the board will be made by the 

 station. Work on the renovation of worn pastures was also followed. 



The dairyman collected data on farm butter making and made 

 some tests of cows for farmers. 



The botanist cooperated with this Department in spraying work on 

 leaf spot, scab, and other diseases of fruit. Lime-sulphur and Bor- 

 deaux mixtures were compared. A study was also made of the tomato 

 point rot w^hich is troublesome in the greenhouse. Results thus far 

 indicate that it is not due to the presence of a fungus or enzym. The 

 station also cooperated with this Department in farm management 

 studies. 



The following jDublications were received from the station during 

 the year: Bulletins 137, Strawberries for New Hampshire; 138, 

 Humus in New Hampshire soils; 139, Caterpillars injuring apple 

 foliage in late summer; and 140, Analyses of feeding stuffs and ferti- 

 lizers; Circulars 1, Mixing chemical fertilizers on the farm; 2, Test- 

 ing soils for fertilizer needs; 3, The apple leaf aphis; 4, The oyster- 

 shell scale; 5, The San Jose scale; and 6, A circular of information 

 concerning the New Hampshire Agricultural Experiment. Station; 

 and Scientific Contributions 1, The influence of minimum tempera- 

 tures in limiting the northern distribution of insects; and 2, The 

 fruit spot of apples.
