Potato-sprayingr Experiments in 1907. By F. C. Stewart, 

 G. T. French and F. A. Sirrene {U.S. A. Exp. Stn., New York, Bull. 307 ; 

 December 1908). — There are fourteen statements of cost of spraying. 

 About seventy-five gallons of Bordeaux were applied to the acre at a spray- 

 ing, costing about 8s. The results of 177 experiments show an increase of 

 50J bushels per acre in favour of spraying with Bordeaux mixture. —

Potato-spraying* Experiments in 1908 (U.S.A. Exp. Stn., 

 Vermont, Bull. No. 142 ; May 1909 ; with 4 cuts). — Bordeaux mixtures 

 and lime-sulphur plots gave a 37 per cent, larger yield than did the 

 unsprayed plots, while Bordeaux twice applied yielded 67 per cent, more, 

 and that applied four times 141 per cent, more than did the unsprayed 

 plots. — M. C. C. 



Potatos, Comparative Yield from English, Scottish and Irish 

 Seed (West Scot. Agr. Coll., 9th Ann. Bept. 1909, p. 109).— Three 

 varieties " Ninetyfold " (early), "British Queen" (mid-season), and 

 "Up-to-Date" (main-crop), were grown, seed being obtained from 

 England, Scotland and Ireland. The seed of any one variety unfortun- 

 ately did not weigh the same on the respective plots, the Irish seed being 

 in most cases considerably the heaviest, but the numbers of tubers set (or 

 cut sets) was the same in each case. The weight set and the total yield 

 is shown in the following table, but the report should be consulted for 

 the weights of the tubers of different sizes.

Potatos, Effect of planting- Sprouted Tubers on Yield. By 



Prof. E. P. Wright (West Scot. Agr. Coll., 9th Ann. Bept. 1909, p. 101). 

 The yield from sprouted and unsprouted seed planted in alternate rows 

 was compared, the varieties grown being " British Queen," " Up-to-Date," 

 ' l Langworthy " and " Scottish Triumph." The returns show the result 

 of one year's trial only, but in the case of every variety the yield from the 

 sprouted tubers was greatly above that from the unsprouted, and the 

 indications are that the increase is greatest in the late varieties. — F. J. C.
