116 EXPERIMENT STATION RECORD. [Vol. 38 



OMo weather for 1916, W. H. Alexander and C. A. Patton (Ohio Sta. Bui. 

 S14 (1911), pp. 617-697, figs. 63).— Tables showing temperature and rainfall for 

 the entire State in comparison with similar data recorded at the station are 

 supplemented by a series of diagrammatic maps showing the comparative 

 weather conditions for the various sections of the State. 



The mean temperature for the year at Wooster was 48.9° F. ; for the State, 

 51°. The highest temperature at the station was 99°, August 21 ; for the 

 State, 104°, August 21. The lowest temperature at the station was — 7°, Febru- 

 ary 22; for the State, —18°, February 14. Tlie annual rainfall at the station 

 was 34.93 in. ; for the State, 37.24. The number of rainy days at the station 

 was 141 ; for the State, 119. The prevailing direction of the wind was southwest 

 at the station and in the State at large. 



Weather notes, 1916, E. Oliver {Saskatchewan Dept. Agr., Ann. Rpt. Sec. 

 Statis., 10 (1917), pp. 26-45). — Brief notes are given on the characteristic fea- 

 tures of the weather for each month of the year and data for rainfall at differ- 

 ent places in Saskatchewan are tabulated. 



The weather of the past agricultural year, F. J. Beodie {Jour. Roy. Agr. 

 Soc. England, 77 {1916), pp. 120-129). — Data on temperature, rainfall, and sun- 

 shine during 1916 and preceding years are given for the British Isles, and the 

 characteristic features of the weather during the different seasons of 1916 are 

 discussed with particular reference to their effect on crop production. 



The weather of Scotland in 1916, A. Watt {Trans. Highland and Agr. Snc. 

 Scot., 5. ser., 29 {1917), pp. 274-286). — This report consists as usual of (1) a 

 general description of the weather over the Scottish area from month to month 

 and (2) a selection of rainfall returns, in which each county in Scotland is 

 represented by one or more stations. Outstanding features of the weather of 

 1916 were the prolonged spell of wintry weather in February and March which 

 put a stop to agricultural operations, the cold spell in June, and a general 

 deficiency of sunshine. 



SOILS— FERTILIZERS. 



studies on the Paleozoic soils of North Wales, G. W. Robinson (Jour. Agr. 

 Sci. [England], S {1917), No. 3, pp. 338-384, figs. 2).— This is a report of studies 

 of the general characteristics of the soils of the counties of Anglesey, Carnarvon, 

 and Denbigh, in North Wales, in which the main soil types are described, includ- 

 ing soils derived from the weathering of local glacial drift, and the associated 

 sandy, alluvial, and peaty soils. 



With the exception of sands, alluvia, and peats, the soils of the area are of 

 loam texture, and clay soils are rare. " The clay fraction rarely exceeds 10 per 

 cent in the case of soils derived from the shale, or 7 per cent in the case of the 

 Anglesey and Carnarvonshire loams. Usually the clay fraction falls consider- 

 ably below these figures. The silt fractions, on the other hand, particularly 

 in the Paleozoic silt loam, form a considerable proportion of the soil." Seden- 

 tary soils and soils derived directly from local drift deposits contained remark- 

 ably high proportions of fine gravel. This was particularly the case in the sub- 

 soils. One sedentary soil in Carnarvonshire contained over 40 per cent of fine 

 gravel in the subsoil. 



Analyses of a number of the fractions obtained in mechanical analysis showed 

 that these soils were poorer in silica and richer in alumina and ferric oxid than 

 English soils. " The most notable difference, however, is that in the Welsh soils 

 the most siliceous fraction is never the fine gravel as in the Craibstone and 

 English soils. . . . The highest percentage of silica is found in the coarse sand 

 in four cases, in the fine sand in three cases, and iu the silt in three cases."
