EXPERIMENT STATION RECORD. 



each of cabbage and cauliflower were left as a check, and the remaining 

 rows received about 17.2 in. of water at 4 applications as the plants 

 seemed to need it. The season was very dry, as only 5.275 in. of rain 

 fell, the normal precipitation being 17.86 in., so the test was well calcu- 

 lated to show the effect of irrigation. The principal data appear in the 

 following table:

GraiJliic diagrams are given showing effect of irrigation on head 

 formation and weight of heads. 



Irrigation appeared to increase the number of plants heading by 12 

 per cent in the cabbage and 14 jier cent in the cauliflower, and to 

 increase the average weight of heads 50 per cent in the cabbage and 66 

 per cent in the cauliflower. 



The author was surprised that the unirrigated plants did so well, but 

 ascribes it to the liberal application of manure and to the fact that the 

 subsoil at setting time contained a fair amount of water which these 

 deep-i-ooting plants were able to use. "The irrigation of cabbage and 

 cauliflower did not prove iirofitable to the same extent as that of straw- 

 berries" (see p. 696). 



A celery test {Florisfs Exchange, 9 (1897), No. 6, pp. 1]G, 117, figs. 

 6). — An attemj>t was made on Long Island to test the claim previously 

 made in this paper that it is possible for a whole field of celery to 

 revert to the wild plant in a single season. 



The experiment consisted in growing 65 varieties and strains, among 

 them the Golden Self-Blanching, the one concerning which the claim was 

 made. A careful examination was made of all plants and no variation 

 was found that would warrant any such claim. Of the particular variety 

 under special consideration, there was no variation observed in more 

 than 100,000 plants examined. The author believes it would be impos- 

 sible to cause any good strain to revert to a worthless one in a single 

 season by bad culture or other means. 



Analyses of California cherries, prunes, plums, and Logan 

 berry, G. E. Colby {California Sta. Bpt. 1895, pp. 177-18^).— The 

 author reports analyses of 6 samples of cherries, 5 of fresh prunes, 7 

 of dried prunes, 2 of plums, and 1 of Logan berry, some of the more 

 important results of the analyses being shown in the following table 

 (p. 691).
