their management, for we have known plants when under the 
most favourable circumstances and apparently in vigorous health 
to dic suddenly above the graft. The Mango is recorded to 
have been grown in the hothouses of this country at least 160 
years ago; but it is only within the last twenty years that it has 
come into notice as a fruit capable of being brought to per- 
fection in England. The first, and, we believe, the most suc- 
cessful attempt was made by the late Earl of Powis, in his garden 
at Walcot, where he had a lofty hothouse 400 feet long and 
between thirty and forty wide, constructed for the cultivation 
of the Mango and other rare tropical fruits ; but within these few 
years we have known it to bear fruit in other gardens. The 
plant here figured was sent by Dr. Wallich to these Gardens 
some years ago. In the summer of 1848 it was placed in the 
Palm-house, where, last year, it bore fifteen fine fruits. It is 
growing in a box three feet and a half square, and now forms 
a round bushy tree, eight feet across and thirteen feet 
high. ‘This spring it has borne a profusion of flowers; and 
we now observe some young fruit, but it is not so abundant 
as might have been expected from the vast quantity af flowers. 
This deficiency of setting may be in some degree ascribed to 
its flowering at so early a period of the year, during cold dull 
weather, but, we believe, is chiefly owing to the want of im- 
pregnation of the ovules, on account of the imperfection of the 
stamens. ‘The normal number of the latter is five, but out of 
that number only one, generally, bears pollen. As asingle raceme 
seldom brings to perfection more than two to four fruits, it may 
be inferred that the great profusion of flowers is a provision of | 
nature to supply the deficiency of perfect stamens; and being 
a hothouse plant and flowering at an early season, it is de- 
prived of the agency of bees and other insects, to assist in 
conveying the pollen to the stigma. It is, therefore, essential 
that some substitute for insects should be resorted to. Brushing 
the flowers gently with a camel-hair pencil is probably the best 
plan; and, although from the smallness of the flowers the 
operation may be tedious, it should be repeatedly done while 
the plant is in flower." Judging by the soil in which Mango 
plants have been growing when imported, its nature does not 
appear to be important for ensuring successful cultivation in India. 
Under our cultivation we find the plants thrive in good yellow 
loam containing @ little leaf-mould, or other rich vegetable matter, 
taking care that it be well drained. An average temperature of 
60° in winter will suit them; this should be increased as spring 
advances and the plant begins to show symptoms of growth. J. S.
