from four to six inches in diameter, as it allows the bed 

 to be cleared for another crop. There is little differ- 

 ence between a good strain of Snowball cauliflower 

 and any of the better strains of Early Dwarf Erfurt that 

 are on the market under different names. 



CHAPTER XVII. 



RADISHES, CARROTS, BEETS AND BEANS. 

 FORCING RADISHES. 



One of the first vegetables to be forced was the radish, 

 and although it has perhaps held its own, there certainly 

 has not been any marked increase in the amount raised 

 for winter. The demand in the spring for hotbed and 

 frame radishes has grown to large proportions. The 

 crop can be easily raised in the winter, and there is no 

 reason why the area of glass now devoted to it cannot 

 readily be doubled. 



The crop succeeds well on either a well-drained, 

 solid bed or a deep, raised bench, filled with from four 

 to six inches of rich, light loam ; the greater depth 

 should be used for the long-rooted varieties, while the 

 bed can be more easily regulated, and as good results can 

 be obtained, if the soil is not over four inches deep for the 

 turnip-rooted sorts. The seed should be sown in drills, 

 varying from five to six inches apart, according to the 

 variety, as some kinds have small foliage that will 

 enable the plants to grow close together, while other 

 forcing sorts will need at least six inches. If the seed 

 has been tested and known to be good, it could be scat- 

 tered in drills half an inch deep, at intervals of three- 

 fourths of an inch. It would be better, however, as
