ftith this green mould, yet the bark was free from cracks. The bark of 
the part thus dressed became in a short time clear, and entirely free, 
whilst the remainder of the tree was still clothed in its green garb. I 
would recommend all gardeners, who have trees in (his condition, to 
give them a dressing once or twice in ths winter season, and 1 doubt not 
that it will answer their highest expectations.

Article VI. — Description of a Pit for Pifte<i, Mchits. S^'c. 
erected at the Mmyjids of StaJf'onVs, TreutJtnt/}, Stafford- 
shire. By Mr. John Woolley, Gardener there. 
Having in these gardens some old forcing frames of little use, in con- 
sequence of the greater part of the pit-room being taken up with Hues 
and cavities, I was induced to take them down and re-build them after 
a plan of my own, which I have found to answer extremely well for 
pines, melons, and cucumbers ; and as by this plan, much less room is 
lost, and a sufficiency of heat produced with full one-third less fuel, 1 
consider it to be an improvement upon the old system of building fire- 
frames. 
The following is a description. — Length of the frame, from B to C, 
64 feet 6 inches; width, from D to E, 13 feet 6 inches; height, from 
F to G, o feet 4 inches; base, H to I, 5 feet 6 inches ; walls 9 inches; 
pillars, 9 inches thick and 2 feet high, u})on which nine-inch arches are 
sprung ; distance between the pillars, 3 feet ; width of the flue, 10 in- 
ches; flue-walls, 3 inches; cavity in front of the flue, 9 inches; from 
the flue to the pillars, 6 inches; and from the pillars to the pit-wall, 
6 inches. From the front v. all to the pillars, is an open space of 2 feet 
7 inches, which admits the heat from the flue, through the arches, into 
the frame. From the outside wall to the top of the pillars, is sprung a 
nine-inch semi-arch, one foot from the top of the flue, which is carried 
the full length of the frame, and returns to the chimney. K, fire-place. 
L, coal-house. M, flue. 
It will be seen, that on the line B C, (ground-plan) there are two 
soot-doors [m m) of cast-iron, which can be opened with ease whenever 
the flues require cleaning. The dots on the top of the pillars, (in the 
longitudinal section,) aie cramps of iron, which pass from the out- 
side wall to the inside of the pillar wall, to hold the work firmly 
together, (see transverse section, a a.) On the line of the Hue, BC 
(ground plan) are two fly dampers, [u] which can be used to work one 
or both lengths at pleasure. The ])it walls, (66, transverse section) are 
9 inches (hick to v.ithin 12 inches of the top, and are t'len reduced
