944 EXPERIMENT STATION RECORD. 



Forage crops, I. P. Roberts and L. A. Clinton (Neiv York Cornell Sta. Bpt. 1897, 

 pp. 271-296, fi<js. 6). — A reprint of Bulletin 135 of the station (E. S. R., 9, p. 341 ). 



Jackson Limbless cotton, R. J. Redding {Georgia Sta. Press Bui. 36, pp. ..').— A 

 report on a test of 21 varieties of cotton, including the so-called Jackson Limbless. 

 The author describes the merits of this variety. He believes it to be identical with 

 Welborn Pet. 



Potato culture, I. P. Roberts and L. A. Clinton {New York Cornell Sta. Rpt. 

 1897, pp. 151-168, fins. 4). — A reprint of Bulletin 130 of the station (E. S. h'.. 9, p. 343). 



The sugar beet, H. J. Waters {Missouri sta. Bui. 40, pp. 16, fig. 1). — This bulle- 

 tin contains a tabulated report of the cooperative experiments with sugar beets in 

 1897. From 90 counties 301 samples were obtained and analyzed. The average 

 weight of the beets in the samples was 26 oz., the average percentage of sugar in the 

 juice 11.14, and the average coefficient of purity 71. Of the samples analyzed 117 

 contained 12 per cent or more of sugar in the juice. These samples were furnished 

 bv 73 counties. Notes are given on previous experiments in this line and on the 

 weather conditions for the season of 1897. 



Distribution of seeds and plants, E. J. Wickson {California Sta. Bui. 118, 

 pp w £). — Brief reports are given of the seeds and plants distributed by the station 

 and descriptions and lists given of those offered for distribution during the coming 

 season. 



HORTICULTURE. 



Latitude and plant growth, L. C. Corbett (West Virginia Sta. 

 Bpt. 1896, pp. 178-193, pis. i). — This is an extract from a thesis on this 

 subject. Instances of the effect of climate on the growth of grapes, 

 Russian apples, and corn are noted, and the results of experiments with 

 cuttings and seeds of various plants are given. 



In 1889-'90 cutting's of Concord grapes from New Jersey, Virginia, 

 and New York were compared, all having received the same treatment 

 after the experiment began. The New York cuttings started growth 

 earlier than the others and a greater percentage of them grew. Fay 

 Proline and White Grape currant cuttings from New York and New Jer- 

 sey showed practically no difference, either in time of starting or in 

 vigor of growth. Cuttings of poplar, 24 from New York and 24 from 

 Virginia, were planted at the same time and given the same treatment. 

 Two weeks alter planting all the New York cuttings, but none of the 

 Virginia cuttings, had started growth. At the end of 3 weeks 11 of 

 the Virginia cuttings had started. About G weeks after planting all of 

 the Virginia cuttings had started, but the New York cuttings were then 

 at least one-third more advanced. In the case of Meech Prolific quince, 



6 out of 11 cuttings from New York and only 1 out of 11 from New Jer- 

 sey had started growth 2 weeks after planting. Of the Orange quince, 



7 out of 11 cuttings from New York and none of the 9 cuttings from 

 New Jersey had started 2 weeks after planting. 



In 1891-'92, 37 cuttings of Lombardy poplar from Maine were com- 

 pared with 39 cuttings from New York. About 6 weeks after planting 

 the Maine cuttings had made an average growth of 1.96 in. and the New 

 York cuttings 1.64 in. A comparison was made of 30 cuttings of the 

 Concord grape from Maine, 32 from New York, and 23 from Louisiana.
