Fertilizers for tobacco, 11. J. Patterson (Soiifhern Hauier, 56 (1S95), No. 3, pp. 

 109, 110). — A siininiary of results of experiments, particularly tliose of the Maryland 

 station, already reported in Bulletin 26 of that station (E. S. K., (!, p. 209). 



Wheat, barley, and sorghum, C. H. SniNN {California Sta. Rpf. 1S03 and 1S94, 

 pp. 410, 411). — The yields of 13 A'arieties of wheat are tahulated. Himalaya harley, 

 an early and prodnetive varietj' tested at the station, is recommended as a profitable 

 variety for hog raisers. Nepaiil l>arley, which is heardless, has large and heavj' 

 heads and palatable straw and is highly recommended for hay. The report contains 

 a brief note on sorglmm.

HORTICULTURE. 



Electro-horticulture, F. VV. Bane ( West Virfjinia Sta. Bui. 37, pp. 

 27, /i(js. II). — Detiiiled notes on exiieriments for testing the efi'oet of 

 incandescent electric light on plants grown in greenhouses. Incan- 

 descent lamps were used in jtreference to arc lights eveii in opal globes, 

 as giving a much steadier and cheaper light, casting no sharp shadows. 

 Tlie experiments were carried on during the seasons of 1892-'93 and 

 1893-94, 3 greenhouses being used for the ])nrpose. The liglit was 

 fiirnislied by one IC-candlepower lamp and by a cluster of 7 lamps 

 of the same strength, which could be nsed in various combinations. 

 Usually the light was tnrned on during the entire night. Lettuce, 

 endive, beets, radishes, spinach, cauliflower, and various ornamental 

 l)lants were selected to be nsed in the experiment, the choice being par- 

 tially governed by those already tried under the arc light. The same 

 varieties used were also planted in an oulinary greenhouse unlighted 

 at night as a check. 



Of lettuce the varieties Grand IJapids, Hanson, and Tennis Ball 

 gave, resi)ective]y, one sixth, one fourth, and one eighth greater yield 

 by weiglitin the lighted house than that grown without the aid of elec- 

 tricity. Spinach and cauliflower also made an imi)roved growth in the 

 lighted house, but beets and radishes made a smaller growth in both 

 houses. In 1893-'94: peas and beans were also planted, and, while irreg- 

 ularities in subirrigation atiected the results with the beans, the peas 

 proved better in the lighted house, liadishes, on the contrary, this year 

 were far better in the dark Louse, earlier, with smaller tops and larger 

 roots; but it is believed that a greater amount of moisture in the dark 

 house was an important element in the difference. Various jiotted 

 ornamental plants blossomed earlier under light.
