136 EXPERIMENT STATION RECORD. [Vol. 38 



On the red soils, the average yield of White Transparent was 5,814 lbs. per 

 acre.- The seedling cane B. 6450 gave the highest yield, 8,793 lbs., representing 

 a monetary gain over the standard of $107.53 per acre. 



For the period of 1912 to 1916 White Transparent gave an average yield of 

 4,920 lbs. on the black soils and 5,321 lbs. per acre on the red soils. The highest 

 yielding variety for the five-year period was Ba. 6032, with a yield of 7,728 lbs. 

 and a monetary gain over White Transparent of $67.67 per acre. B. 6450 gave 

 the highest average yield on the red soils, 7,791 lbs., with a monetary increase 

 over White Transparent of $59.53 per acre. This variety also gave an increase 

 of $35.72 over tlie standard variety on the black soils. 



In a comparison of Ba. 6032 and B. 6450 on 34 plats, Ba. 6032 gave, as a 

 three-year average, 1,429 lbs. of saccharose per acre more than B. 6450. 



Notes on improved methods of cane cultivation, C. Clabke and N. Husain 

 (Dept. Land Rec. and Agr. United Prov. Agra and Oudh, Bui. 35 (.1916), pp. 8, 

 figs. 3; rev. in Agr. Jour. India, 12 (1917), No. 1, pp. 170-172). — Improved and 

 tested varieties of sugar cane are recommended for the Central Provinces and 

 cultural practices deemed best for the region outlined. 



Distribution of cane for seed, H. B. Cowgill (Porto Rico Bd. Agr. Expt. Sta. 

 Circ. 8 (1917), Spanish Ed., pp. 3-13). — Local and introduced varieties of sugar 

 cane are briefly described and the advantages of the development of new vari- 

 eties outlined. Regulations governing the distribution of cane for seeding pur- 

 poses are noted. 



Sweet clover, A. Atkinson (Montana Sta. Circ. 62 (1917), pp. 49-55). — The 

 production of sweet clover in Montana for hay and pasture is discussed and the 

 handling of the crop for seed production noted. 



Sweet clover grown under irrigation in 1915 yielded 2.2 tons for the white- 

 flowered biennial, 2.67 tons for the yellow-flowered biennial, and 0.62 ton for 

 the small yellow-flowered annual. In 1916 the first two sorts yielded 3.02 and 

 4.2 tons per acre, respectively, the annual sweet clover being entirely winter- 

 killed. The white and yellow flowered biennials grown on dry land at the 

 Judith Basin substation in 1916 yielded 1.16 and 1.32 tons of hay per acre, 

 respectively. 



Harvesting and storing sweet potatoes, J. C C. Price (Alabama Col. Sta. 

 Bui. 197 (1917), pp. 87-103, pis. 4, figs. 4; pop. ed., pp. 87-100, pis. 4, figs. 2).— 

 The results of storage tests witli sweet potatoes conducted at Auburn and at 

 other points in cooperation with growers are reported for 1914-1916, inclusive, 

 for a comparison of the keeping qualities of potatoes stored in an especially con- 

 structed storage house and those stored in banks, pits, or trenches. Approved 

 methods of harvesting, curing, and storing the crop are described. The curing 

 temperatures varied from 80 to 85° F. and the storage temperatures from 

 50 to 60°, the extreme limits for storage being from 40 to 65°. Humidity 

 varied from 80 to 90°. Temperature and humidity records were secured during 

 the curing and storage period for each year of the experiment and are shown 

 by graphs. 



The Triumph, Nancy Hall, and Porto Rico, deemed the most important com- 

 mercial varieties grown in the State, are reported on in the storage tests 

 and show a loss by decay in the house of from 1.5 to 11 per cent on March 1 

 as compared with a similar loss of from 7.5 to 100 per cent in the banks on the 

 same date. 



A selected sample of Triumph potatoes weighing 120 lbs. was placed fn 

 storage Nov. 10. 1915, and observed for loss in weight. A loss of 5.5 lbs. was 

 sustained the first 5 days at an average temperature of 84°, while during the 

 next 5 days under an average temperature of 62° there was an additional loss
