638 EXPERIMENT STATION RECORD. 



Twenty varieties of eucalypts have been planted on high sloping land to 

 compare with the same varieties which have been growing on low land for a 

 number of years. Thus far the liinds making the most vigorous growth on the 

 high land are Eucalyptus robusta, E. tereticornis, E. rostrata, and E. paniculata. 

 On the lower poorly drained soil E. robusta, E. piperita, and E. tereticornis are 

 the only promising ones, though many trees of other varieties are living and 

 making some growth. Many of the seedlings planted during the year were 

 affected with crown gaU, but thus far no apparent damage has resulted, the 

 most thrifty trees often having the largest galls. 



In a previous report relative to the degenerating influence of Porto Rican 

 conditions on imported vegetable varieties, it was concluded that okra and beans 

 had degenerated both in vigor of the plants and productiveness (E. S. R., 27, 

 p. 842). It has been found, however, in the case of the Early Valentine bean 

 that since the second generation there has been a gain in productiveness during 

 successive generations until the eighth generation has exceeded the yield from 

 the first generation. Duplicate plantings from the original seed, from the sec- 

 ond, and from the eighth generations were made in Porto Rico and In Minne- 

 sota during the summer and the harvest results ranked the same with different 

 generations. With White Velvet okra on the other hand the second generation 

 has in different plantings resulted in the most vigorous plants and heaviest 

 yield, whereas the successive generations gradually deteriorated. With other 

 crops under observation, the results are not pronounced. 



In a test with subirrigation v. surface irrigation a number of varieties of 

 tomatoes, peppers, beans, onions, and eggplant were grown, each of which pro- 

 duced better and were much less expensive to cultivate in the subirrigated 

 area. In addition to their value for irrigation the underground tubes gave 

 beneficial drainage results during the wet season. 



Horticultural investigations at the Woburn Experimental Fruit Farm 

 [Nature [London^, 91 (1913). No. 22S7, pp. 675-678, figs. 3).— This comprises a 

 report of a lecture delivered by S. U. Pickering in which the author gives a 

 general account of the horticultural work at the Woburn farm. 



Vegetable culture in north Louisiana, E. J. Watson (Louisiana Stns. Bui. 

 141, PP- 28). — This bulletin contains directions for the culture of the staple 

 vegetables in north Louisiana, both during the fall and winter season and 

 during the spring and summer season. The subject matter is based on long 

 experience with vegetables at the Calhoun substation. 



Inheritance in cabbage hybrids, H. L. Price ( Virginia Sta. Rpts. 1911-12, pp. 

 240-257. figs. 12). — The author here combines his previous observations on first 

 generation hybrids (E. S. R., 28, p. 639) with additional observations on the 

 second and in some cases the third generation hybrids. Numerous crosses were 

 made and in most cases reciprocal hybrids were under observation. The fol- 

 lovring set of differentiating attributes were involved : Blistered and smooth 

 leaf, head and headless cabbage, cabbage and cauliflower type of head, cauli- 

 flower and headless cabbage, terminal and axiUary bud (head) growth, and 

 kohl-rabi and head cabbage. 



In all of these crosses the resultant hybrid considered as a whole presented 

 the appearance of a blend, but when the above differentiating characters alone 

 were considered one character usually dominated the other, although the domi- 

 nance could not be called absolute or complete in all cases. No segregation of 

 these characters took place in the second generations. 



The blistered or crinkled foliage of the Savoy cabbage remained dominant 

 over smooth foliage even in some third generation hybrids. Head cabbage wag 

 dominant over collards or headless cabbage, although there was a tendency to 

 less solid heads in the hybrid forms. The cabbage head likewise dominated
