THE ORCHID REVIEW. 253 
most of the other Mexican kinds, should be watered very sparingly. 
As it is very necessary to give the plants as much light and sun as 
possible without causing injury, it will be better now to think about slightly 
reducing the summer shading. For instance, there are usually many 
situations where, through various reasons, some kind of permanent shading, 
such as “summer cloud,” is used, just to break the rays of the sun for a 
short period during the hottest time. This must not be allowed to remain 
on when it is no longer necessary to serve its purpose. The roller blinds 
may also be let down later in the morning, and removed earlier in the after- 
noon. 
I am extremely sorry to hear that the Cattleya fly has got such a foot- 
hold in some collections. Compared to this arch fiend, other troublesome 
insects are insignificant. Iam also sorry that I am unable to give more precise 
instructions for its speedy destruction other than already given in previous 
Calendars, which consists chiefly in watching closely for the infected 
growths, and by exercising great caution when purchasing new plants; the 
latter being the preventative policy, is, of course, the best. If any signs 
whatever of their presence exists on newly imported plants, they should 
certainly be isolated until they have been thoroughly cleansed, and 
fumigated several times. 
As warmth from the pipes in many departments has not been required 
for some time, the valves have probably not been turned, oiled, and kept in 
good working order. When such is the case they invariably become rusty, 
and will sometimes spring a leak when again touched. These, and other 
matters connected with the heating apparatus, should be seen to in time, 
and put all straight and secure, rather than left until absolutely required, 
when some hitch may occur.
