THE FLORIST. 
5th. To diminish an over luxuriant branch, leave a greater number 
of buds upon it, by pruning less severely in the dormant season, and 
pinch back, during the summer, the young shoots. 
6th. Encourage a horizontal growth of branches except with the 
leader ; this is assisted by having the last bud on the shoot an outside 
bud, which will grow from the centre of the tree. 
7th. Let the highest bud on the leader be on opposite sides each 
successive year to prevent it from growing to one side.

A HOUSEFUL OF ROSES IN FULL BLOOM IN APRIL. 
Mr. Floris, the well-known perfumer in Jermyn-street, has a neat 
suburban residence, and charming little garden attached to it, at Acton 
Green. He is fond of flowers, especially of Roses, of which he has an 
excellent collection; they thrive and bloom with him in the greatest 
perfection. Dwarfs and half standards are grown in beds of considerable 
size, climbing kinds are trained up pillars and over arches so as to cover 
walks, and altogether the effect they produce when in full blossom is * 
excellent. 
It is to Mr. Floris’ Roses under glass, however, that we wish now 
particularly to direct attention. In a house upwards of 40 feet in 
length, he has had this year, and indeed annually, from the beginning 
to the middle of April, a stageful of the “ Queen of Flowers ” in pots, 
all in the greatest possible beauty. Such a bank of Roses covered with 
bloom thus early we do not think is elsewhere to be found. The plants 
are all about one height, charmingly clothed with clean and healthy 
foliage, and the colour and size of the blooms all that could be desired. 
The plants producing this magnificent display are, we understand, 
chiefly from layers taken up from the open ground in autumn: They 
are potted and placed under glass about the beginning of January, so 
that in less than twelve months they have become what has just been 
described. To the mode of ventilation employed, Mr. Floris attributes 
much of the unusually clean, healthy condition of his plants. The 
house is warmed by 4-inch hot-water pipes in three tiers, and in the 
front wall, opposite the middle tier, are apertures at intervals the whole 
length of the house for the admission of air, which passing over the 
pipes gets partially heated before it reaches the plants. There are also 
ventilators at the back of the house near the glass, and thus a free 
circulation of warm air is continually kept up. A mode of shutting and 
opening the whole of the air passages along the front of the house 
simultaneously was put in practice here by Mr. Burn, an architect, and 
it answers extremely well. The little iron lids or shutters closing the 
openings are fixed to a thin bar of iron, which runs the whole length of 
the house; to one end of this is attached an upright handle in such a 
way as to make it form a lever, which upon being drawn towards you 
opens the ventilators, and pushed from you shuts them. The hot-water 
pipes are also so managed as to warm a range of glass about 90 feet in 
length from one boiler. The house next the latter is a greenhouse, and
