VEGETABLE FORCING 



poor seed may result in almost a total failure, because 

 many of the plants may not produce heads at all, and 

 those that do form are small and undesirable. Most of 

 the cauliflower seed used in the United States is grown 

 in Denmark and France. Much of this seed does very 

 well under glass, but there is nearly always some concern 

 as to whether the results will be wholly satisfactory. On 

 account of the uncertainty of the crop when forced from 

 imported seed, Shoemaker of the United States Depart-

ment of Agriculture has been conducting experiments in 

 growing seed in greenhouses. Small packets of the Gov- 

 ernment seed have been supplied to various agricultural 

 experiment stations as well as to practical growers, and 

 the crops produced from this seed have been highly satis-

 be used for forcing purposes should be grown under 

 glass, and we are indebted to him for the following in- 

 formation relating to the subject: 



"In brief, our method of culture in the greenhouse has been about 

 as follows : We have found that we can make two crops of com-
