tion, and evaporation at New Brunswick during 1910 and previous years are 

 reported and brieflj' discussed. 



Weather report, ^^'. H. Day (Ann. Rpt. Ontario Apr. Col. and Expt. Farm, 

 37 (1911), pp. 58-63). — Tabular summaries are given of observations on tem- 

 perature, precipitation, and lengtli of tbe growing season at representative sta- 

 tions in Ontario during 1911. There is also a record of wind movement during 

 the year at Guelpb. 



Swedish meteorological observations, 1911, H. E. Hambeeg (Met. lakttag. 

 Svcrigc (Obscrv. Met. 8ued.) K. Svcnska VeteiisJc. Akad., 53 (1911), pp. 

 X+157). — These are the usual meteorological summaries of observations made 

 tuKler the direction of the Central Meteorological Institute of Sweden. 



Duration of sunshine and insolation at Stockholm and Hafringe, J. West- 

 man (K. Svenska Vetensk. Akad. Handl., Jft (J911), No. 8, pp. 38; abs. in Met. 

 Ztschr., 29 (1912), Wo. 10, pp. Jf89, //y^?).— Monthly and yearly sums of sunshine, 

 total radiation, and vertical components of total radiation are given for Stock- 

 holm during 1907 to 1910 and for Ililfringe for 1910. 



Frosts in New York, W. M. Wilson (Netc York Cornell 8ta. Bui. 316, pp. 

 G05-5ff3, figs. IS). — Conditions favoring the formation of frost and methods of 

 protection which have been used with success are described with special refer- 

 ence to conditions i)revailiug in New York. 



Electric Niagaras and recent storms, A. Lafobest (Jour. Soc. Nat. Hort. 

 France, If. sen, 13 (1912), Sept., pp. 572-57 If). — Several instances are cited in 

 which tbe Eiffel Tower, acting as a so-called electric Niagara, had no influence 

 in dissipating hail storms. 



Well water, R. Hakcourt (Ann. Rpt. Ontario Agr. Col. and Expt. Farm, 37 

 (1911), pp. 71-73). — Sanitary analyses of 34 samples of well water from dif- 

 ferent parts of Ontario are reported. A large proportion of the samples showed 

 evidence of contamination. 



SOILS— FERTILIZERS. 



The soils of Oregon, C. E. Bradley (Oregon Sta. Bui. 112, pp. //S). — This 

 bulletin reports the results of several years' work on the soils of Oregon and 

 includes chemical analyses of a number of soil types from different parts of 

 the State arranged by counties, and analyses of drainage waters from tanks 

 under different cropping systems and fertilizers. Analyses of samples of water 

 from the Columbia and the Willamette rivers are also reix)rted. 



" The soils grade from the rich black loams of the coastal plains and lower 

 river courses of western Oregon to the extremely sandy soils of the eastern 

 and tbe coarse granitic soils of the southern portion of the State, with many 

 intermediate types. Volcanic rocks predominate in the northwest, and Oregon 

 soils are largely derived from weathered basalt, diabase, and diorite, particu- 

 larly in the eastern and western part of the State. In southern Oregon gran- 

 ites, limestones, and other metamorphic rock exist also and have, therefore, 

 determined in part the mineral character of the soils of this section. Where 

 the weathering process has taken place under humid conditions, as in western 

 Oregon, clay loams rich in humus have been formed, while under the climatic 

 influences of the arid or semjarid conditions of that portion of the State east 

 of the Cascade range, a sandy soil has resulted." 



It was found that there was little loss of the mineral elements by leaching, 

 except in one case where considerable phosphoric acid was lost. Nitrogen was 

 lost in appreciable quantities, particularly under summer fallow. This nitrogen 

 loss was appreciably reduced by legume rotations.
