way ; that is, a glazed roof about two feet high, the glass strong 
enough to resist the fall of a small rope, or other light body. 
It was hermetically closed with the common lime cement of the 
country, and was never opened during a voyage of five months. 
AVhen we arrived in England, the plants were all in beautiful 
health, and had grown to the full height of the case, the leaves 
pressing against the glass. In dry weather, I always observed 
moisture within the glass, which was caused, no doubt, by the 
evaporation of the earth, and was again absorbed by the plants. 
It is difficult to account for the perfect health of the plants, 
without the full admission of the atmosphere ; but oxygen suffi- 
cient was probably admitted, either through the pores of the 
wood, or otherwise. It is, however, a fact, that no water was 
given to them during the voyage, and that they were landed in 
excellent order.” This reminds us of Mr. Ward’s plant cases, 
explained at section 72. 
120 Pomegranate, to flower. Under common management, 
the double-flowered Pomegranate rarely blossoms freely, and 
oftentimes not at all. Mr. David Whale, Gardener, of Winches- 
ter, in a paper inserted in the Floricultural Cabinet, No. 39. says 
“The double flowering kind is much more esteemed than the 
other in this country, for the sake of its large fine double flowers, 
which are of a most beautiful scarlet colour ; and if the trees 
are well managed, and supplied with due nourishment, they 
will continue to produce flowers for four or five months suc- 
cessively, which renders it one of the most valuable flowering 
trees. This sort may be rendered more productive of flowers, by 
grafting it upon stalks of the single kind, which checks the lux- 
uriance of the trees, and causes them to produce flowers upon 
almost every shoot. There have been various ways recom- 
mended to manage the pomegranate, so as to make it flower 
freely, and forty years’ experience has taught me what I conceive 
to be the most successful method. I do all my pruning in the 
summer season; training the branches at a regular distance, of 
about four inches apart, in the same way as I train a plum tree ; 
towards the latter end of June I look over the trees, and remove 
all the shoots that are running to wood; at which time they are 
young and tender, and are easily removed without the assistance 
of a knife. Care must be taken to leave all spurs and blossom 
shoots, which are easily distinguished from w ood shoots. This I 
do about three times during the summer, and by this treatment
