set for flowering, and with proper management they will show flower before 
making much growth, then a rather free supply of water may be given, and 
in the case of large specimens which may be rather short of pot room, give 
plenty of manure water. Syringing over-head should, of course, be discon- 
tinued when the blossoms begin to expand, but a thoroughly moist state of 
the atmosphere must be maintained, if large flowers are desired, and it is 
doubtless the neglect of this which is the principal cause of the miserably 
small flowers which are often seen upon this plant. 
While in bloom the plant may be removed to a somewhat cooler situation, 
provided the proper degree of moisture can be maintained in the atmosphere, 
which will tend to prolong its beauty. As already stated, the specimen will 
continue growing and flowering the whole season, but it can seldom be had 
in first-rate condition after the first head of flower is over, and unless better 
things are scarce, or it can be cut back and grown a second time, it need 
not receive any very particular care through the summer, merely afibrding 
it a situation in a rather warm house, and a moderate supply of water. By 
annually cutting back and disrooting, a specimen will last any length of 
time, and will soon form an immense bush, producing a grand efi"ect when in 
full beauty. 
The best soil for this plant is good strong fibry peat with a small propor- 
tion of turfy loam ; the peat and loam should be carefully broken up and 
intermixed with a liberal proportion of clear sand to insure the soil taking 
water equally ; and in potting, the soil should be made moderately firm, so 
as to prevent the water escaping without first moistening the ball.

DELPHINIUM COGSWELLIANUM. 
Although all the Delphiniums are worthy of cultivation, yet I think 
pretty perennial Larkspur will prove a great acquisition. 
It is a native of California, but of what part I do not know. It was 
found in 1853 by Dr. William Brown, formerly of Hartford, Connecticut, 
an amateur botanist, who named it in honor of Dr. Mason F. Cogswell, an 
eminent physician and botanist of Hartford, with whom he studied. I 
sowed the seed in August last, in pots prepared for the purpose, placing 
a square 6f glass over it, and plunged it in a spent hotbed. The seed 
vegetated in a few weeks. Having potted them off, they grew vigorously,
