564 EXPERIMENT STATION RECORD. 



Green color of pod proved a dominant and yellow ;i recessive character. As 

 regards the color of Mowers, dark-colored flowers were usually dominant when a 

 cross was made between white-flowered and dark-flowered plants. As regards seed 

 color, "the immediate results of crossing two races having different seed colors can 

 not he foretold from any other hybrid between races with similarly colored seeds." 



Statistical data covering the first, second, and third generation of hybrids is given 

 for nearly all of the characteristics noted above, and comparisons made with the 

 theoretical proportion as required by Mendel's law. 



Shading vegetables (Amer. Cult., 66 (1904), No. 47, p. 1). — An account is given 

 of 2 years' work in growing vegetables under tent shade at the Rhode Island station. 

 During both years the growing season was cool. It was noticed that vegetables were 

 more easily transplanted under the tent than outside. The tent covering also broke 

 the force of rains, so that the ground was not packed so hard, nor did it bake so 

 readily inside as outside. 



Lettuce formed leaves faster inside the tent, but headed better and showed less 

 tendency to run to seed outside. Celery matured more quickly outside than inside 

 the tent, but the stalks were longer and the total amount of marketable celery con- 

 siderably greater from the plants inside the tent. The quality also seemed to be a 

 little better from the shaded ground. 



Market gardening in Egypt, A. L. Monfront {Alexandria Hurt. Soc, 1904, pp. 

 13-36). — Directions are given for the culture and fertilization of a large number of 

 vegetables grown by market gardeners in Egypt. 



Fall sowing and wintering of plants of the cabbage family, P. M. Novik 

 (Norsk Havetidende, 20 (1904), No. 9, pp. 167-172). — The article describes experi- 

 ments by the author in sowing plants of the cabbage family in the fall and wintering 

 the same under glass, so as to obtain early vegetables. In the author's experience a 

 gain of 14 days to 4 or 5 weeks may be obtained by this method of procedure over 

 that of spring sowing. — f. w. woll. 



A soil experiment, E. A. Season (Agr. Epitomist, 23 (1904), No. 9, p. 4). — An 

 account is given of growing cabbage on a piece of sandy land which had been 

 devoted to the growth of root crops for a number of years, but was giving unsatis- 

 factory results. A plat 155.5 by 93.33 ft. was left unmanured; another plat of the same 

 size was fertilized with 200 lbs. acid phosphate and 40 lbs. of sulphate of potash, 

 while a third plat received 200 lbs. of acid phosphate only. 



The sudden appearance of winter early in the fall prevented the satisfactory har- 

 vesting and weighing of the crop, but it was noticed that the cabbage on the unfer- 

 tilized plat grew tall and spindling, making but few heads, which were practically 

 worthless. Satisfactory heads were grown on plats 2 and 3, but those on plat 2 were 

 much more compact and solid and considerably exceeded in weight those grown 

 upon plat 3, which received phosphoric acid only. Of the various forms of potash 

 the sulphate is considered the best for cabbage. 



Violet carrots, L. Wittmack (Festschrift zur Feier des siebzigsten Geburtstages 

 desHerrn Professor Dr. Paul Ascherson. Leipzig: Borntraeger Bros., 1904, pp. 327-332, 

 pi. 1). — The author describes 2 violet colored carrots (Daucus carotav&r. boissieri) 

 found in cultivation in Egypt and in Spain. The root of the variety from Spain 

 is stated as being blood red like a beet and with a white heart. The root is long and 

 grows half way out of the ground. It is considered especially valuable as a feed for 

 horses, mules, and asses. A colored plate is given showing the form of the roots 

 and details of the plants. 



Native or Blackfellows' bread, D. McAlpine (Jour. Dept. Agr. Victoria, 2 (1904), 

 No. 10, pp. 1012-1020, pis. 5). — An account is given of this truffle-like fungus growth 

 which is native to Victoria. Scientifically it is known as Polgporus mylittse. A tech- 

 nical description is given of the plant, with numerous illustrations, and a bibliog- 

 raphy of the literature of the subject. Specimens of this vegetable growth weigh-
