shows well in a perpendicular shape. The barrel is 
made with four upright wires placed at right angles and 
hooped round with smaller wire, 2 or 3 inches distant; 
this shape answers well for Cactus. The conical 
is made with two long pieces of strong wire, thrust in 
the pot as directed for the circular trellis, only cross¬ 
ing each other at right angles on the top, and tied fast, 
then encircled with smaller wire in the same way as the 
barrel; this answers well for Passifloras, and Hoyas 
or other strong growing climbers. Bring out all the 
vines under the lowest circle next to the pot, then take 
one of the longest vines and train it round and round 
the frame elevating it as you proceed, so that the end 
will come to the top ; tie it fast, and continue till your 
frame is covered, then cut off the rest of the vines, if any 
remain. A Passiflora six or eight feet long, may by 
this training be placed in the space of a foot in diameter, 
and 3 feet in height, making, when in Flower, a pillar 
of blossoms. As climbing Plants are very abundant in 
Flowers and easy of cultivation, they make handsome 
Plants when neatly trained. 
HEAT AND TEMPERATURE. 
Plants will generally grow in light airy rooms, 
where a person feels comfortable as regards tempera¬ 
ture, not too hot and close, nor too cold. Although 
there is a great difference in Plants as regards heat,
