Forecastinf*; the crops of the Dakotas, H. L. Mooke (PoUt. Sci. QiKirt.. 35 

 tl!>20), \o. 2, pp. 20.'f-235, ftps. S). — The theories are advanced in this paper 

 rhat yields of spring wheat in North Dakota may be more accurately fore- 

 !<ted from the accumulated weather changes than the Government ollicials 

 • recast them from data supplied by agents in the field; that accumulated 

 • hanges, particularly the raijifall of the critical growth season of crops, tend 

 to follow a compound cycle of S and 31 years; and that the wheat, oats, and 

 barley crops tend to follow the same constituent cycles. 



Kxaniining the odicial method of crop forecasting, it is concluded that in 

 <ight out of njne cases in the Dakotas the forecasts from the weather are more 

 ac'-urate than the official forecast from the condition of the ci'ops. The ad- 

 vantage of the forecasts from the weather is greater for the early months than 

 '!• the later months, that is, that the margin between the two forecasts is 

 ;irrowed with the approach of the harvest. In the one case in which the fore- 

 cast by which the otTicial method is better, the report is made only about two 

 weeks before the harvest. 



Findings of this and of earlier studies, one of which has been previously 

 noted (E. S. II., 41, p. 892), would indicate that the compound cycles of 8 and 4 

 years in the annual rainfall of the Ohio Valley, the May and June rainfall in 

 ilie Dakotas, the yield of cotton in the United States, and the yield of wheat, 

 iiats, and liarley in the Dakotas, in the United States, in the United Kingdom, 

 and in France are, as far as concerns the dates of their maxima and minima, 

 practically synchronous. 



Monthly Crop Reporter (U. S. Dept. A(/r., Mo. Crop Rptr., 6 (1020), No. 6, 

 lip. J/'J-dO, figs. 4). — This contains the usual estimate of acreage and produc- 

 tion, and data relating to the farm and market value of important products 

 and crop conditions, together with the current United States crop summary. 



There are included estimates by States representing the proportion of the 

 total number of hogs and cattle in the United States belonging to the bre<Hls 

 nanred, a chart .showing regions where long staple cotton is grown, also tabu- 

 lations of the percentage of the principal spring wheat varieties in the total 

 crop, and of the perc<'ntago of the total year's farm work done each month in 

 the year.
