the bulbs four inches apart iu the drills, three inches 

 below the surface. Keep the cultivator constantly 

 going, not to kill weeds, but to make Tuberose bulbs. 

 After a frost take up the bulbs, cut the tops to within 

 two inches of the tops of the bulbs, and store in a dry 

 room, where the temperature does not fall below 40. 

 From North Carolina southward, small sets will make 

 large flowering bulbs in one season ; to the northward it 

 requires twb years. For that reason, what are known as 

 "Southern grown bulbs," can be profitably sold much 

 cheaper than those grown at the North. Whether the 

 latter are to be preferred because of their superiority, is 

 a disputed question. Our opinion is that it is not a 

 question of growth, but of the care taken of the bulbs 

 after they are dug, that enhances or detracts from their 

 value. Northern grown bulbs, like all other plants that 

 have a shorter period of growth, will produce their flow- 

 ers earlier, but whether with more certainty we have 

 great doubts. 



For blooming in the garden, the offsets should all 

 be carefully taken off, and the bulbs put away until the 

 wounds are dried over; then plant in good rich soil, 

 placing the bulb just below the surface ; if covered too 

 deep they are not as likely to flower.

 can be had in bloom, with a little care, nearly the whole 

 year. Plants that show flower buds in the field, upon 

 the approach of frost, will perfect their growth if care- 

 fully taken up and put in a warm greenhouse, as will 

 bulbs that have not even shown their flower stalks. Dry 

 bulbs may be planted from January to August, which 

 will keep up a succession of bloom. They succeed best 

 planted out on the benches with about four inches of 

 good soil. The same conditions of growth must be 

 observed indoors as without, heat, manure, water, and 

 a free circulation of air. They must, moreover, have
