The aphis are readily kept in check by tobacco smudge. The first 

 cabbage worms were noticed November 21st, and for a couple of weeks 

 they had to be carefully picked. The boxes of young plants had stood 

 out of doors during September and it is probable that eggs were laid 

 upon the plants at that time. 



The first week in December heads were beginning to form. The 

 first heads were sold January 13th, four and a half months from the 

 sowing of the seed. The Erfurt gave the earliest and evidently the 

 best results. The plants had been checked somewhat late in their 

 history by very dark weather and possibly by some inattention in 

 management, and many of the heads began to " button " or to break 

 into irregular portions with a tendency to go to seed. The house was 

 needed for other experiments, and on January 20th the plants were. all 

 removed. At this time nearly three fourths of the crop had matured 

 sufficiently to give marketable heads, although many of the heads were 

 small. Winter cauliflowers, in common with all forced crops, should 

 be harvested when small, for products of medium or even small size 

 sell for nearly or <j[uite as much as large ones in winter, and the co^t of 

 raising them is much less. A head four inches across is large enough 

 for January sales, and many of the heads which we sold were consid- 

 erably smaller than this. These heads sold readily at our door for 

 twenty cents apiece. 



January 25th, 1893, a second crop of cauliflowers was set in the beds, 

 comprising Early Snowl^all and Dwarf Erfurt. Seeds for this crop 

 were sown in flats October 21st. On November 5th the plants were 

 transplanted to other flats, and on December 16th shifted to 3-inch pots, 

 where they remained until set in the bed. On April 8th the plants had 

 reached the size shown in the photograph in Plate II. At this time 

 they completely covered the ground and choked out lettuce which we 

 had placed between them. About the 20th of March heads were found 

 to be forming in the Early Snowball. In the former experiment Erfurt 

 gave the first heads. A week later than this, Snowball had heads 

 three to four inches in diameter while Erfurt showed none. The first 

 heads were sold on the 29th of March, about five and a third months 

 from the time of sowing. It will be observed that the time between 

 sowing and harvest is greater in the second crop than in the first. This 

 is because the plants were wholly grown in the dark and short days of 

 mid-winter. It should be added, also, that the climate of Ithaca is 

 excessively cloudy and that the forcing of plants presents special difti- 

 culties here. An attempt was now made to keep the plants in a uniform
