died iiiid forty-five days ; aud non-maturing. This season tlie time of riponiiig for each 

 class was piolouged about teu days. 



There was considerable dilfereuco in the lieight of stalks between the seasons of 1888 

 and 1889. The average height on eighty-two i)lats in 1888 was 11.2 feet ; in 1889, 9.7 

 feet. Similar differences were observed in the height of the ears on the stalk. 



In 1888, the average per cent of water in the shelled corn when husked was, in the 

 early maturing varieties, approximately 18 per cent; medium maturing, 22; late 

 maturing, 27; non-maturing, 36. In 1889 the average jjcr cent was 17, 24, 29, and 

 :58, respectively. The increase in the per cent of water with the later maturing is 

 very marked. The difference in the loss of weight is more than is usually recognized. 



To make a bushel of thoroughly air-dry corn — that is, shelled corn containing 11 

 per cent of water — it took, when the corn wns husked, October 20 to November 13, 

 72 pounds of ear corn in the early maturing, 80 jiounds in the medium maturing, and 

 89 in the late maturing. As most of the corn produced in central Illinois this season 

 was late, 80 pounds evidently would not have been sufficient to produce a bushel of 

 air-dry corn. 



On eighteen plats of tract a the same varieties of corn have been grown three 

 yeai's successively. The average yield per acre when the corn was husked in 1887 

 was 32 bushels ; in 1888, 94 ; in 1889, 82. The yield of air-dry corn for the three years 

 was 29, 83, and 66 bushels respectively. The largest yield of air-dry corn in 1887 was 

 36^ bushels, from Murdock ; in 1888 and 1889, from Leaming, 93 and 79 bushels, re- 

 spectively. The per cent of water in the shelled cf>rn of the 18 varieties in 1887 was 

 18.35; in 1888, 21.39 ; in 1889, 28.27. As the corn was husked at about the same time 

 each season, these figures give a good idea of the difference in the maturity of the 

 corn in the respective seasons. 



While no one of the varieties tested stands far above the average of the bettor va- 

 rieties of its class, doubtless a large number of the varieties are better than the 

 average raised by the farmers of the State, and might be introduced on their farms 

 with profit. Not to exclude other meritorious varieties, the following medium ma- 

 turing dent varieties may be safely recommended for geileral culture in central Illi- 

 nois: Yellow — Leaming, Clark's Iroquois, Legal Tender, Riley's Favorite, Fisk. White 

 — Champion White Pearl or Burr's White, Gourd-Seed, Clark's Premium 110-Day. The 

 following, which are desirable early maturing varieties in this latitude, may be rec- 

 ommended for general culture in northern Illinois : Yellow — Murdock, Edmonds or 

 Kane County Pride, Grange Favorite, King of the Earliest (for very early). White 

 — Wisconsin White Dent, Champion of the North. 



The following, which are almost too late for this latitude, would probably be de- 

 sirable farther south : Yellow — Improved Orange Pride, Steward's Improved Yellow, 

 Sweugel. White — Helms's Improved, Parrish. 



Experiment No. 3 — Corn^ time of planting (pp. 247-249). — This is re- 

 ported iu siibstautially the same manner as was the similar experiment 

 of the previous year. There were in 1888 seven, and in 1889 eight 

 phintings at intervals of a week. In 1888 the first was April 22, the 

 last June 13. 



The results of two seasons' experiments indicate that the yield of corn is not appre- 

 ciably affected by a variation of five weeks, prior to June 1, in the time of planting. 

 Some differences occur which seem to be due to certain variable conditions of weather 

 rather than to the time of planting. Sometimes the later plantings may be properly 

 cultivated with less labor than the early plantings. 



Experiment No. -i— Com ,1 depth of planting (pp. 249,250). — "May 4, 

 1888, six rows, each 8 rods in length, were planted with corn at deptlis 

 varying from 1 to G inches. May G, 1889, six rows were planted in the
