In the medium-early groups, Stabler's Early, Concotl, Shakers', Pee and Kay, 

 Sqiiantum, and Asylum are recommended. Of late varieties, Old Colony is of better 

 quality than Stowell's Evergreen, and it ren\ains in condition for use nearly as long. 

 * * * Of the sliallow-graiued late varieties there would be little choice between 

 Mamniotb, Hickox, and Henderson. * « * for farmers who do not care to plant 

 more than a single variety, Crosby, planted at dillereut times, would be as good as 

 anything. The new varieties sent out every year at high prices, are almost certain 

 to be a disappointment to the grower, since they nearly always fail to fulfill the 

 claims of the introducer. 



In the classification of sweet-corn the varieties are divided according to the time 

 in reaching edible maturity after planting, into early, medium, late. Also on color: 

 yellow, white, colored, not yellow. A further division of varieties is made into eight- 

 rowed, and having more than eight rows. 



Circumstances have made it impracticable to give any estimates of yields of corn 

 grown the past season. 



Classified descriptions are given for the 49 varieties recognized as 

 distinct. 



Pop CORN, test of yarieties, T. J. Burkill, Ph. D., and G. W. 

 xMcCluer, B. S. (pp. 443-147). 



The pop-corn varieties were primarily grown for botanical and other closely re- 

 lated studies, and especially in tests of cross-fertilization, from which interesting 

 results are to be reported at another time. 



The list of varieties of pop-corn grown the past season by the station is as full as 

 it was possible to make it from the seedsmen's lists received. * * * So far, all the 

 varieties of pop corn may be readily divided into two very distinct types or classes. 

 One class is very coaimouly known as rice corn, and has kernels more or less pointed, 

 with the outer coat, where the silks were attached, continued into a sort of spine, 

 which may either stand almost erect or may be depressed by the crowding of the 

 husk on the ear. The ears in either case are rough to handle. The other class, of 

 which the white, at least, is frequently known as pearl corn, has kernels rounded or 

 flattened over the top and very smooth, the point of the attachment of the silk being 

 lower down on the same side of the kernel as the germ. Tiie two classes thus dis- 

 tinguished may be divided, as with sweet and field corn, into early, medium, and 

 late, and these again into white, yellow, and colored nob yellow. 



All the varieties of corn cross with each other so readily that it is difficult under 

 ordinary methods to keep a variety strictly to any given type ; and so we find fre- 

 quently that corn sent from different sources under the same name will differ as 

 much as corn from the same source under dilierent names, and that there is room 

 for question as to whether a given lot belongs in this or that group which we class as 

 a variety. 



Classified descriptions are given for 15 varieties. 

 Growth and increase of dry matter in corn, G. E. Mor- 

 row, M. A., AND T. F. Hunt, B. S. (pp. 448-450). 



This is a preliminary report of a series of observations on the rate of growth of 

 field corn, as determined by measurements and by ascertainiug the quantity of dry 

 matter at different dates. The design is to attempt to determine by a series of such 

 observations the lelations between growth, both of the whole plant and of its differ- 

 ent constituents, and meteorological conditions; and also to help to determine the 

 stnge of growth at which tlie plant has the greatest food value. 



The plan a<lopted is to cut, to measure, and to examine by chemical analysis at 

 stated intervals during the season of growth, the stalks of duplicate or triplicate hills
