Cattleya maxima. The main peculiarities of this plant consist 
in its long channelled pseudo-bulbs, and in its very convex wavy 
petals, which are quite different in appearance from the thin, 
nearly flat petals of C. Mossice and labiata ; in other respects it 
approaches these species very nearly. It is, however, remark¬ 
able for the dark crimson veins richly traced upon its pallid lip, 
and for a beautiful network of purple streaks, which is drawn 
over all their surface. At first, too, the colour of the flowers is 
so pale as to be almost white; but the tints heighten day by day, 
till at last the blossoms acquire a very rich rosy purple colour.—

CALENDAR FOR FEBRUARY. 
The very mild winter up to the present time will no doubt be 
favorable to the multiplication of snails and slugs ; and too 
much care cannot be taken to keep them undor as much as pos¬ 
sible. There are several species of the molluscous animals 
natives of Britain, and they are all highly injurious to vegetation, 
attacking the tenderest buds, and committing great havoc in a 
small space of time. But they do not all confine themselves to a 
vegetable diet, for in the spring slugs of a tawny or fawn colour 
may be occasionally dug up, for they then, at least, live under 
ground, and will be found regaling themselves on the large earth¬ 
worm. These shell-protected vermin, for all the slugs will be 
found to have a shield of pearl below the skin on the back, im¬ 
mediately over the most vital parts, have many enemies. The 
blackbird and thrush destroy great numbers of snails in the 
winter; ducks, rooks, and many other birds, are equally destruc¬ 
tive to slugs as well; but in gardens of course other means must 
be resorted to, and many are in vogue. In dry weather quick¬ 
lime dusted over the ground, or other places where they abound, 
infallibly destroys all slugs with which it comes in contact. Lime- 
water is also good, especially for plants in pots. Various traps 
are also useful, such as cabbage leaves, turnips hollowed out or 
cut in slices, and other similar vegetables, laid about among the
