pickling' iiiid preserviiiu;' any of the pear and plnm varieties and 

 Green Gage and White Apple will do well. " Of the yellow apple- 

 shaj^ed varieties. Janne Grosse Lisse proA^ed most satisfactory'. 

 Golden Qneen or Yellow Jeiferson will also be found desirable.'' 

 Among- the older varieties, Ignotnm (a sport from Eiformige Daiier) 

 is especially connnended. 



(2) Effect of using seeds from first ripe fruits. — To test this mat- 

 ter, fifty-two varieties were planted in duplicate, six hills of each 

 from seeds of first ripe fruits and the six adjoining hills from seeds 

 selected some tvro weeks later. The results included in the tables are 

 thus summarized in general terms: 



The first pickiug of tomatoes of angulnr varieties gave four times as many 

 fruits from plants grown from seeds of the first ripe fruits as from those se- 

 lectetl from the main crop, while with the apple-shaped sorts only two-fifths as 

 many were obtained. 



BULLETIN No. 49 (STATION), MAY, 1889. 



Chemical compositiox of corn stalks, hay, and screenings, 11. ( '. 

 Kedzie, M. D. (pp. 3-8). — Corn stalks and silage at different jjeriods 

 of groivth (pp. 3-T). 



The acreage food value of a fodder crop will be at its maximum when there 

 is the largest amount of digestible albuminoids and carbohydrates and the lea.st 

 relative amount of indigestible fiber. The percentage of chemical composition, 

 therefore, will have to be interpreted with reference to this acreage increase of 

 the crop. The plan adopted for 1888 was to gather a specimen of corn as soon 

 as it is tasseled. make a chemical analysis of a part, and place the balance in a 

 silo for future analysis, and repeat this process every week until the corn was 

 fully ripe. The fresh stalks v^ere examined for the amount of water and dry 

 matter at each cutting, and a quantity of the cut stalks was ra[)idly dried and 

 saved for subsequent analysis. 



Burrill and Whitman's silage dent corn was used. When har- 

 A^ested the corn was cut into pieces three-fourths of an inch long, and 

 immediately placed in small silos, consisting of strong oak casks. 

 These silos j^roved very satisfactory for the purpose. Two tables 

 are given, one showing the condition of the stalks at time of ensiling 

 and the percentage of dry matter in the stalks and in the silage, and 

 the other the chemical composition of corn stalks and silage from 

 the same lot, and also of some silage made from corn not fully ma- 

 tured. From the author's remarks in connection with the second 

 tal:>le the following statements are gathered: (1) as the corn ap- 

 proaches maturity there is a marked increase in the percentage of 

 nitrogen-free extract and a decrease in the percentage of crude fiber 

 and ash. (2) In tlie silo there is a small loss of crude protein and a 

 change of albuminoids to amides, a progressive decrease of acid, and a 

 notable increase of fhe ether extract (fat, etc.). 



Marsh liag uud wlicat screenings (pp. 7, 8). — This includes chem- 

 ical analyses of a sample of marsh hay of mixed Avild grasses (sedges) 

 and of a sample of wheat screenings, consisting of broken grain, 

 shrunken wheat, seeds of weeds, etc.
