THE COTTAGE GARDENER AND COUNTRY GENTLEMAN’S COMPANION, July 14, 1857. 
IMPLEMENTS AND OTHER CONSTRUCTIONS SUITED FOR GARDENS. 
Exhibited at the Horticultural Society’s Show at Chiswick. 
(Continued from page 189.) 
Boiler and Hot - water Apparatus exhibited by 
Messrs. Weeks & Co., King’s Road, Chelsea. — These 
upright tubular Boilers are very powerful, durable, and 
economical. The furnace-bars are hollow tubes, through 
which the return water passes before entering the upper 
part of the boiler, thereby causing a very rapid circulation, 
and producing double the effect from the same quantity of 
fuel. 
The object of the whole is to expose the largest sur¬ 
face for heating to the action of the lire. 
Ornamental Stacks of Pipes made of various sizes, suit¬ 
able for Warming Dwelling-houses, Halls, Churches, Offices, 
&c. Any number can be fixed side by side, or to form a 
square, exposing a very large heating surface in a very small 
space.

adapted for Warm¬

Patent Triangular Tubular Boiler, by Mr. T. G. 
Messenger, Loughborough. —In this Boiler the immense 
surface exposed to the direct heat of the fire is obvious, and 
by the arrangement of parallel triangular tubes no particle 
of heat can escape without first doing threefold the work it 
would in any other manner of construction. The horizontal 
position of the tubes and the triangular shape cause the 
heat in its upward current to rebound from tube to tube, so 
that before it can reach the flue the chief of the heat is ex¬ 
pended in the boiler. The rapid circulation of the water, 
which is the groundwork of the principle, caused by the 
action and reaction of the fire, is considerable. Should the 
| boiler at any time require cleaning, it can be done by re- 
i moving the ends, which are made in separate parts. The 
i fire-bars form water-spaces; consequently they cannot be 
i injured by the action of the fire, and the bars themselves 
become a working part of the heating apparatus. 
Broomheads, patented by Mr. W. Henderson, Gar¬ 
dener to the Duke of Athol, Dunkeld. —These Broom- 
j heads are iron frames, into which twigs of Birch, Heath, 
; Broom, or other shrubs may be firmly fixed by means of 
nuts and screws, for turning which a wrench is supplied 
with each, and each head has a socket, like that of a garden 
rake, by which it is fastened permanently to a handle. The 
fan or flat ones (Nos. 1 and 2), for sweeping short grass 
from lawns, answer well. We have not tried the large 
round-headed one. 
Nos. 1 and 2. Fan Broomheads, filled with Birch and 
Palm fibre, for sweeping lawns, carriage-drives, &c.
