1919] HORTICULTURE. 245 



varieties of yautias, and of the relative value of that crop and of gabis and 

 dasheens in the Philippines are described. 



Maximum yields obtained from different varieties of these crops planted 1 

 by 1 meter (3.28 ft) apart in the field amounted to 33,205 kg. per hectare (about 

 14.8 tons per acre) for yautias, 5,200 kg. for dasheens, and 5,217 kg. for gabis. 

 Yautias planted 1.5 by 1.5 meters apart produced a maximum yield of only 

 15,199 kg. per hectare. Several varieties planned as an intercrop among coco- 

 nuts, on plateaus (about 400 meters in elevation), in cultivated caingins, in 

 uncleared and uncultivated caingins, on coffee plantations, and after cogon 

 (Imperata sp.) have produced maximum yields of 26,008, 26,116, 28,495, 18,830, 

 21,010, and 22,772 kg. per hectare, respectively. 



Plant breeding and controlled seed farms (Jour. Bd. Agr. [London], 23 

 (1917), No. 11, pp. 1081-1081, pis. 2).— The necessity of adequate seed control 

 in England, with special reference to the production and distribution of new 

 and improved varieties of seeds and of guarantied "pure" stocks of estab- 

 lished varieties, is discussed. The organization at Svalof, Sweden, for the im- 

 provement of seed is described and some of its achievements briefly noted. 



Seed Reporter (U. S. Dept. Agr., Seed Rptr., 2 (1918), No. 4, pp. 8).— Sta- 

 tistical data are presented showing the commercial stocks, sales, and seed re- 

 quirements for the United States of 26 different kinds of field seeds in the dif- 

 ferent geographical divisions (E. S. R., 39, p. 138), as determined by the seed 

 survey of July 1, 1918. Based on this survey, data are also given showing the 

 average difference in price at which stocks were sold for seed and the price at 

 which they were sold for food, feed, or manufacturing purposes. 



The commercial stocks, receipts, and exports of field, vegetable, and root 

 crop seeds in Canada are reported in tabular form from data obtained in a seed 

 survey made July 1, 1918, by the Dominion Department of Agriculture. 



Other subjects dealt with include the damage by rain to California vegetable 

 seed crops ; the millet seed outlook ; timothy, clover, and alfalfa seed prices ; 

 and notes on market conditions at Chicago and Milwaukee. The usual tabu- 

 lated data are presented showing the imports of field, vegetable, and flower 

 seeds into the United States and of forage plant seeds permitted entry into the 

 United States.
