Mr. Freperic Mackie, whose skill and experience in 
Horticulture are very great, observes, that he is very suc- 
cessful in flowering the different species of Ecurnocactus, 
by growing them “ very near the glass, and during the 
summer time, in a very high temperature, by keeping the 
upper glasses of the house close: strong light and heat 
bemg necessary for expanding their blossoms in perfection. 
Some of them will close immediately upon being removed 
to a cooler place. It is also very necessary to have the 
pots well drained, as the roots are liable to decay if the 
earth is at all sodden with moisture. I think that setting 
the free growing species in poor soil is quite a mistake, for 
we invariably find that they thrive better in good soil, pro- 
vided it be well drained, and if they are planted in small 
pots.”
