States of the American Union are entirely unsuited for cultivation in 

 Ontario, owing to the shorter season of growth in Ontario as compared 

 with that in some of the central States. Hence, the importance of test- 

 ing a large number of varieties under similar conditions to ascertain 

 not only the total yield of crop per acre but also the yield of ears or 

 grain and the comparative earliness or lateness of the different varie- 

 ties. In securing a suitable corn for the silo or for use as green or dry 

 fodder, it is important to select a variety that produces a large total 

 yield per acre and also gives a large yield of grain, and reaches a fair 

 stage of maturity before the first nipping frosts occur in the locality 

 where it is grown. Keeping these three points in view in experiments 

 which have been conducted with a large number of varieties of corn for 

 several years in succession, we have found that the Mammoth Cuban, 

 Mastadon Dent, and Leaming are varieties which generally give good 

 satisfaction on the warm soils of the southern part of Ontario, where 

 large varieties of corn can be grown successfully ; that the Wisconsin 

 Earliest White Dent and the White Cap Yellow Dent give a good 

 yield of total crop per acre which is of excellent quality, both of these 

 varieties producing large yields of ears, and being specially suited to 

 the central part of the Province where the frosts are not too severe; 

 and that the King Phillip, Salzer's North Dakota, and Compton's Early 

 varieties generally give good satisfaction in those parts of Ontario 

 where the frosts are apt to occur at an early date. Of the one hundred 

 and three varieties grown in the Experimental Department in 1904, 

 the largest yields of ears per acre were produced by the following kinds : 

 Early Windsor Sweet, 5.2 tons; Kendal's Early Giant Sweet, 5.2 tons; 

 Ringleader Sweet, 5.0 tons; and Winconsin Beauty Sweet, 4.9 tons 

 per acre. It will therefore be seen that the four varieties which have 

 produced the greatest yields of ears per acre in 1904 were all sweet 

 corns. These varieties are suitable for fodder purposes, but are not 

 considered as valuable for silage as some of the Dent corns. 



Methods of Cultivation. In 1902, 1903, and again in 1904, an 

 experiment was conducted by cultivating corn in four different ways. 

 The North Star Yellow Dent variety of corn was used in the experi- 

 ment in 1902 and in 1903, and the White Cap Yellow Dent and King 

 Phillip varieties in 1904. Each test consisted of four plots. The ex- 

 periment was conducted in duplicate each year. The average results 

 of the six tests conducted within the last three years are as follows : 

 (i) Deep cultivation at first gradually getting shallower as the season 

 advanced, 21.9 tons; (2) Shallow cultivation throughout the season, 

 21.2 tons; (3) Deep cultivation throughout the season, 20.8 tons; and 

 (4) Shallow cultivation at first gradually getting deeper as the season 

 advanced, 20.5 tons per acre. From these results, it will be seen that, 

 in seasons such as we have had in the past three years, corn which was 

 cultivated deeply immediately after it was planted and in which the 

 cultivation was made shallower as the season advanced produced the
