56 HORTICULTURE [BoT. Absts., Vol. VIII, 



Farm. These had been taken from local fields devoted to following varieties or groups: Red 

 Fife, Preston, Bluestem, Marquis, Canada Red (Ladoga), unnamed, and durum. In 1917 

 these were reduced to 91. Seven pure lines secured from Minnesota were added. These 

 were Marquis, Bluestem, Preston (Velvet Chaff), Roy alton (red and white), and two durums. 

 Minnesota lines showed 19 per cent increase in kernel weight when grown one year in Maine, 

 No further increase was secured. — Preston kernels from Minnesota lines showed slight tend- 

 ency to yellow berry while similar tendency in durum was very strong when grown under 

 Maine conditions. — Variations in yield among various pure lines were rather marked. — Minne- 

 sota pure lines showed but slight loss in crude protein content, except durum lines which 

 showed marked loss. Taking the 40 pure lines grown and analyzed in 1917 and 1918, the 

 correlation coefficient of protein content was 0.381 ± 0.092. — Certain Red-Fife lines gave sat- 

 isfactory yields and best baking results. Preston and Bluestem lines gave reasonably good 

 results. Marquis and Canada-Red lines were rather disappointing. Durum lines and certain 

 unnamed ones were poorest. — L. R. Waldron.

FRUITS AND GENERAL HORTICULTURE 



356. Allen, W. J. An experiment with table grapes on sultana stock. Agric. Gaz. New 

 South Wales 31 : 600. 1920. — Judging by the yield, grafting trials showed that Corrichon 

 and Ohanez vines do better by 50 per cent on their own stock than when grafted on sultana 

 stock. — L. R. Waldron, 



357. Allen, W. J., S. A. Hogg, and W. leGay Brereton. Orchard notes. Agric. 

 Gaz. New South Wales 31: 599-600, 677-678, 748-750, 830-831, 898-900. 1920.— Practical sug- 

 gestions of a timely nature are given upon care of orchards and products therefrom. — L. R. 

 Waldron. 



358. Anonymous. Delmas pecan. Amer. Nut Jour. 12 : 44. 1920. — The original Delmas 

 pecan tree was grown from a nut planted by A. G. Delmas at Scranton, Mississippi, about 

 1877. The nut is large to very large in size, oblong ovate, has 4 conspicuous ridges, and is of 

 good cracking quality. It has plump, straw colored kernels of rather soft texture and good 

 quality. — E. L. Overholser. 



359. Anonymous. Fertilizing effects of sulphur on vines. Cyprus Agric. Jour. IS: 190- 

 191. 1920. — This article is a summary of results secured by M. Jean Chanzet, a French 

 investigator, from an experiment undertaken to ascertain the action of sulphur upon the 

 cultivation and yield of vines grown in the open. Two series of experiments were conducted, 

 the 1st of which was designed to study the effect of sulphur without manure and the 2nd its 

 effect with manure. The former gave an increase of over 25 per cent and the latter an increase 

 of 27 per cent. — W. Stuart. 



360. Anonymous. Increasing leaf growth by peforating the root. Sci. Amer. Monthly 2 : 

 14. 1920. — Experiments by Mario Calvino in Cuba are concerned, in which horizontal per- 

 forations of the primary root of cabbage, lettuce, parsley, etc., resulted in more luxurious 

 development of the heads; and injections of nutritive solutions into the trunks of sterile pear 

 trees caused them to bear again. — Chas. H. Otis.
