308 EXPERIMENT GTATION EECORD. 



[Miscellaneous analyses], A. M. Peter, S. D. Averitt, aud O. M. Shedd (Ken- 

 tucky Sta. Rpt. 1906, pp. 259-262). — Analyses are reported of evaporated dis- 

 tillery slop, butter, arsenate of lead, dike rock, boiler compounds for preventing 

 scale in boilers, and petroleum for oiling i-oads. 



Annual report for 1908 of the consulting chemist, J. A. Voelcker {Jour. 

 Roy. Ayr. 8oc. England. 69 {1908), pp. 295-307). — This report consists chiefly 

 of analytical data on feeding stutfs, fertilizers, sewage sludge, soils, and other 

 products. 



Report on the activity of the agricultural experiment station of Saxon 

 Upper Lusatia at Pommritz for the year 1908, Loges {Her. Ayr. Chem. Vers. 

 Stat. Pommritz, 1908, pp. 7). — Analytical data of fertilizers, feeding stuffs, milk, 

 milk products, and other agricultural substances are reported. 



METEOROLOGY— WATER. 



The climatic importance of forests, Schwappach {Ztschr. Balneal., Klimat. 

 u. Kurort Hyg., 1909, No. 10; ahs. in Vmschau, 13 {1909), No. 20, p. //33).— The 

 influence of forests in equalizing temperature, increasing the humidity of the 

 air in summer, moderating air currents, controlling the soil water level and the 

 flow of springs and streams, and preventing erosion is discussed. 



The fertilizing value of rain and snow, F. T. Shutt {Canada Expt. Farms 

 Rpts. 1907, pp. 17.3-176; Proe. and Trans. Roy. Soc. Canada, 3. ser., 2 {1908-9), 

 Sect. Ill, pp. 181-185). — A report on previous work on this subject has been 

 noted (E. S. R., 20, p. 15). The present report includes additional data, ex- 

 tending the observations over 12 months ending with February, 190S. 



The data reported show that the nitrogen in the rain and snow at Ottawa dur- 

 ing the year was 4.32 lbs. per acre. Of this 74 per cent was in the form of 

 ammonia and ammonium salts, and 26 per cent in the form of niti-ates and 

 nitrites. The total precipitation during the period was 37.3.5 in., of which 24.05 

 in. fell as rain and 13.3 in. (the equivalent of 133 in. of snow) in the form of 

 snow. It is estimated that approximately 75 per cent of the "nitrogen in the 

 total precipitation was furnished by the rain. 



Evaporimeter records {Florida Sta. Rpt. 1908, pp. XV, JT7). — Partial rec- 

 ords are given of evaporation at 4 different places on the hurticuUura! grounds 

 of the station from July 1. 1907. to .July 13. lOOS. 



Meteorological summaries for the year 1906 {Kentueky Sta. Rpt. 1906, pp. 

 279-282). — Summaries are given of observations on temperature, pressure, pre- 

 cipitation, cloudiness, and wind movement. 



Meteorological summaries for the year 1907 {Kentucky Sta. Rpt. 1907, pp. 

 209-212). — Summaries are given of obscrvntions >m tem]ierature. i)re.^su!-e. pre- 

 cipitation, cloudiness, and wind movement. 



Meteorological observations at the Massachusetts Agricultural Experi- 

 ment Station, J. E. Ostrander and R. C. Lindblad {Massachusetts Sta. Met. 

 Buls. 2'i5, 2.'i6, pp. h each). — Summaries of obsei'A'ations at Amherst. Mass.. on 

 pressure, temperature, humidity, precipitation, wind, sunshine, cloudiness, and 

 casual phenomena during May and June. 1909. The data are briefly discussed 

 in general notes on the weather of each month. 



Weather report, W. H. Day {Ann. Rpt. Ontario Ayr. Col. and Expt. Farm, 

 3't {190S). pp. .'/J-50).— Summaries are given of observations at (Juelph and 

 other places in the Province of Ontario during 1908 on temperature, precipita- 

 tion, wind, and injury from lightning. Attention is called particularly to the 

 climatic conditions of the Abitibi region, about 350 miles north of Toronto, with 

 special reference to the agricultural possibilities of the region.
