were carried forward in the field, and tests of several remedial meas- 

 ures were made in the young experimental orchard of the station. 



Among- the work done with Hatch and other funds, especial promi- 

 nence was given to studies of the maximum capacity of soils and 

 crops to produce feed. Breeding experiments were conducted with 

 the common cereal crops for the purpose of increasing production, 

 hardiness, and earliness. Similar work was also pursued with tall 

 oat grass and soy beans. The cotton-breeding experiments in coop- 

 eration with this department have been carried on at the West Ten- 

 nessee substation at Jackson since the spring of 1909, Some of the 

 selections made in connection Avith tliese experiments were cultivated 

 on the station farm, and considerable seed of the Trice variety Avas 

 produced for distribution among growers. The opportunities offered 

 at the West Tennessee substation for field experiments are considered 

 superior to those under the control of the station elsewhere in the 

 State. The soils are tjqoical of the region and are practically un- 

 modified by previous manuring, and lie well for experimental pur- 

 poses. Variety trials of various farm crops as well as fertilizer and 

 liming experiments were made. A series of crop rotations was 

 begun and rates, dates, and methods of seeding for several crops were 

 tested. 



The meteorologist made a study of the relation of climate to crops, 

 especially the relation between rainfall and corn production. The 

 data collected and the observations made having reference to frost, 

 the growing season, the mean annual rainfall and its monthly distri- 

 bution, and similar factors, were published in bulletin form during 

 the year. 



The horticulturist conducted some experiments in orchard pruning 

 and spraying, giving special attention to the peach crop. The results 

 of some of this Avork showed that Bordeaux mixture is of no value 

 as a remedy for peach scab, and is less valuable than self-boiled lime- 

 sulphur as a remedy for peach rot. Arsenate of lead added to the 

 earlier applications of either Bordeaux mixture or self-boiled lime- 

 sul2:)hur reduced the amount of wormy fruit. In an orchard heating 

 test it was found that fires raised the temperature from 4° to G° 

 and saved the crop. 



The veterinarian demonstrated the efficiency of hog-cholera serum 

 in several herds. 



The station cooperated AA'ith the State department of agriculture 

 in seed testing, for the purpose of excluding serious weeds from cer- 

 tain cultivated crops in Tennessee under a recently enacted seed law. 

 Spraying demonstrations Avcre given in orchards in various parts of 

 the State during the year, and farmers' institutes Avere attended by 

 members of the station staff'. Assistance was also given by the 

 Station staff at short courses in agi'iculture conducted by the State
