supply of moisture. The only safe course is to apply sufficient to 
thoroughly moisten the ball, and then not to water them again until 
the soil has become rather dry. Cultivators frequently injure, and 
sometimes kill, heaths, through a neglect of the important precau- 
tion of applying sufficient water at each application to thoroughly 
moisten the ball. The space on the surface is filled once, as in 
watering plants potted in loam, but as a rule that is not sufficient to 
do more than moisten the upper half of the ball, leaving the lower 
half quite dry. The water should be applied again and again, until 
the surplus runs through the hole in the bottom of the pot. When, 
by accident, the ball of soil becomes dust-dry, the pot should be 
placed in a vessel of water and be allowed to remain in it, and no 
longer, until the air bubbles cease to rise. Because the necessity 
for thorough watering has been insisted upon, it must not be sup- 
posed that they can be over-watered with impunity. So fur from 
this being the case, they must not have a drop beyond their require- 
ments, and care must be taken not to water them until the soil has 
become dry again, as indicated by the ringing sound given off by the 
pot when sharply rapped by the knuckles. Rain-water must in- 
variably be employed. 
During the summer season the plants may be placed out of 
doors, but it is preferable to place them in a pit where they can have 
protection from heavy rains, which, if long continued, saturate the 
soil and injure the roots. Whether out of doors or in a frame, stand 
the pots upon a hard surface, to prevent the ingress of worms. 
During the winter season the stock must have a light airy posi- 
tion in a dry greenhouse, and as an excess of artificial heat is most 
injurious, no more should be employed than is necessary to exclude 
the frost. During periods of long-continued dull, moist weather it 
may be necessary to employ a little fire-heat to dry up superfluous 
moisture and promote a free circulation of air. For this purpose the 
fire should be started early in the morning, and the ventilators— 
those at the apex more especially—be opened sufficiently for the 
stagnant atmosphere to be readily driven out. Sometimes mildew, 
will make its appearance during the winter, and itis therefore, 
needful that it should be well known that a dusting of sulphur is 
the best remedy. 
Mr. Peacock, Suppury Hovusr, HamMersmitu, wishes us to intimate to our 
readers, that those who are interested in succulents may inspect his collection 
any Tuesday during September, between the hours of ten and four, and 
that Mr. Croucher, the gardener, will be present and most happy to give 
any information. ‘The collection is remarkable for its extent and the rarity of a 
large number of the specimens of which it consists ; and we would strongly recom- 
mend those of our readers resident within a convenient distance to avail themselves 
of Mr. Peacock’s kindness. 
Goprt1a Lapy ArsBemarte, of which Messrs. Daniels Bros., Norwich, possess 
the stock, is a most valuable hardy annual. The flowers are large in size, the 
colour rich glossy crimson. The plants attain a height of twelve inches, and 
assume the form of neat bushes, and in due season become quite solid with bloom. 
Plants raised from autumn-sown seed bloom in the early part of the summer follow- 
ing, and those raised from spring-sown seed bloom the foliowing July and August.
