Mango riiDens more evenly and through than on the tree. In England 
Pears are treated in much the same way. When taken off the tree they 
are not fit to eat, and many kinds of Pears require to be kept a long time 
before they are fit to eat. 
This characteristic of the Mango fruit would prove advantageous for 
exportation, as it would ripen on the voyage. 
All the choice varieties most probably originated by seed-variation, and 
their good qualities are kept up by proper cultivation. 
All the fine varieties are propagated by grafting them on seedlings of 
the ordinary ones. 
The Mango tree cannot be grown successfully in localities subject to 
severe frost. On one occasion, in Lucknow, in the first week of January, 
five degrees of frost were registered. All the Poinsettias in the Horti- 
cultural Garden were, of course, killed outright ; the young seedling 
Mango plants in the nursery prepared for grafting were killed ; and up to 
six feet from the ground all the leaves of the large Mango trees were 
blackened, but above that line no leaves were touched. 
In the hot dry weather the trees want regular watering. 
Some place in India not subject to frost, and where water can be 
easily got at, and with good soil, would be suitable for a garden such as 
is here suggested. 
There are so many exquisite varieties of Mango that they could not 
readily be studied, and their characteristics found out, without being 
collected in one garden. From thence they could be disseminated to all 
parts of the Empire where the climate would be likely to suit them. 
I have often tried those that sometimes appear in the London shops 
from the West Indies and other Atlantic islands. I never found one worth 
eating. They would not be looked at by an Indian Mango connoisseur. 
I have often wondered why wealthy English gentlemen, with extensive 
gardens and acres of glass-houses, have never, that I am aware of, under- 
taken to build a special house for the reception and growth of the trees 
that produce one of the finest fruits in the world. 
It is the same with Oranges. The British markets are flooded with 
foreign Oranges, which are often unripe and sour. When ripe they are 
mostly stale, and not infrequently have a flavour of onions or tar. The 
flavour of tar is acquired from the ship-hold, and that of onions comes 
from a mixed cargo of oranges and onions ! 
To eat an Orange off the tree when perfectly ripe would be a revela- 
tion to persons who have not been in Orange countries, and the difference 
between those imported and those taken oft* the tree at the right time is 
something like the difference between night and day. 
And yet one never hears of any wealthy gentleman undertaking to 
erect a special house for Oranges, and to collect these fine things which 
are to be found in various parts of the world. 
There is such a thing as a movable glass house on rails. Such con- 
trivances would be very useful in England, where foreign fruit trees 
might be kept warm under glass in winter, and the house wheeled off them 
in summer to expose them to direct sunlight and rain, both being very 
invigorating to all trees.
