1362. Fhyer, J. R. Germination of oats exposed to varying degrees of frost at different 

 stages of maturity. Agric. Gaz. Canada 6: 337 339. 1919. — Oat plots wen' sown in series at 

 the Lacombe Experimental Station in order that when frosts sin mid occur in the fall the dif- 

 ferent plots would be in various stages of maturity. The effect, of frost, ranging from 2.3° 

 to 8°F., on germination was studied, the maturity of the oat kernel ranging from the milk 

 stage through various stages to the dry and mealy one. A frost of 2.3°F. did not impair 

 vitality in stages ranging from milk to dough. A heavier frost of 4.6°, accompanied by a 

 heavy dew, did not lower vitality in stages from milk to mealy. A frost of 5° followed by one 

 of 8° the next night reduced vitality considerably in the milk and dough stages. — 0. W .

1363. Gavilan, Juan. El problema de las textiles. [Problem of the textiles.] Informa- 

 cion Agric. [Madrid] 9:49-51. 1 fig. 1919. — The importance of textiles to the world and 

 in particular of cotton is considered. Spain, unlike France and England, cannot draw on 

 colonies for raw material for her textile factories. Experiments have shown that heavy 

 yields of cotton can be obtained in Spain but present tariff protection is considered insufficient.

1365. Gtjzmanes, Antonio. La ortiga. [The nettle.] Informacion Agric. [Madrid] 9: 

 167-169. 2 fig. 1919. — Two species ( Urtica dioica and U. nivea [Boehmeria nivea] the latter 

 from China) are commonly grown in Europe for their fiber content. The former is a com- 

 mon w r eed in Spain. The industry has been revived because of war conditions in Denmark 

 and other parts of Europe. The plant is cultivated and the fiber obtained much the same as 

 with flax and hemp. — John A. Stevenson. 



1366. Harris, Wm. Notes on sisal and henequen in Jamaica. Jour. Jamaica Agric. Soc. 

 23: 46-50. 1919. — The cultivation of sisal (Agave sisalana) is considered, including manner 

 of propagation, desirable types of soil, planting methods, care of the plantation, time and 

 manner of harvesting, and finally the extraction, drying and baling of the fiber. A similar 

 account is given for henequen (Agave fourcroydes) , the common fiber plant of Yucatan. —

 for hay, curing cowpea hay, cowpeas for seed, cowpeas for temporary pasture, cowpeas for 

 soil improvement, cowpeas in rotation, cowpea culture, method of planting, fertilizers for 

 cowpeas, inoculation, time to plant, diseases of cowpeas, insect enemies of cowpeas, variety 

 tests, cowpea varieties, soybeans for hay, soybeans for seed, soybeans for pasture, soybeans 

 for soil improvement, methods of culture, rate of seeding soybeans, fertilizer for soybeans, 

 soybean culture experiment, soybean varieties, and cowpeas and soybeans compared. —

1369. Hilson, G. R. 'Northerns' cotton. Agric. Jour. India 14: 300-314. 1919.— In 

 order to improve the "Northerns" cotton; more time and research must be given to improve 

 the plant; and the following features need attention: better harvesting and preparation for 

 the market, better ginning, establishment of an open market to which kapas (unginned cot- 

 ton) might be brought, and the establishment of ginneries properly fitted and constructed 

 and either owned or controlled by the buying firms. — F. M. Schertz.
