Tlie author makes the following comments ou these results: "The stalks from A's 

 and C's French-grown seed were very uniform and alike in all particulars, and were 

 evidently procured from the same source in France. B's French grown was in no 

 way different from B's American grown. The stalks were not of uniform color or 

 size. It was evidently a mixed lot, or else the seed plants had not ])een carefully 

 selected and 'rogued.' The stalks from A's American grown, from B's American, 

 from D's American grown, from E's Selected XX were of the same general charac- 

 ter, both as to habit of growth and mixture of colors. The plants from the American- 

 grown seeds were not uniform in their growth or in their color." 



These experiments, taken as a whole, it is believed show thesu[)eriority of French- 

 grown celery seed over American-grown seed. This superiority, however, is thought 

 to be <lue more to the careful selection of seed by the French than by American seeds- 

 men. With the same care in selection, American seed would probably be as good as 

 foreign seed. 



Detailed directions are included in the bulletin on celery culture in Maryland 

 from the planting of the seed to the storing and marketing of the crop. 



Experiments in hybridizing {Indian Gard. and Plant., 10 {1902), No. 13, p. 

 218; (iljx. froia Staudard). — it is stated that on Sutton's trial-seed grounds one plant 

 each (jf Dwarf (ireen Curled kale, Brussels sprouts, l^roccoli, Red Variegated kale, 

 Purple-colored kale. Thousand-colored kale, Portugal cabbage, Sutton Favorite cab- 

 l)age, Dwarf Blood Red cabl)age, and Drumhead Savoy were all planted in one bed 

 together to see if they would cross. Plants grown from the resulting seeds showed 

 remarkable variation, thus proving the necessity of keeping these plants separated 

 in the seed grounds. 



The book of vegetables, (1. Wvthes {London, and Nen) York: .Jolin Lane, 1902, 

 jjp. 106, Jigs. 17). — This is the seventh of the series of handbooks of practical garden- 

 ing edited by H. Roberts, and deals with the culture and varieties of vegetables 

 grown in England, such as cab))age, broccoli, Brussels sprouts, spinach, various 

 roots and tubers, onions, beans, etc. Chapters are also given on the history and 

 cookery of vegetaljles, by the editor. Like many of the other books in the series, 

 the directions regarding methods of culture, varieties, etc., are particularly adajited 

 to English conditions, and hence will be found of l)ut minor value to American 

 gardeners.
