the timber
standing, the kiln burning costing 2-1/8 d., and the other 3-1/4 d. The
kilns must be lined to about halfway up with fire-brick, the cost of which
will vary with the locality, but will be about L200, and as 40 to 50
bushels of coal have been made per cord the extra yield on good charcoal
and the lessening of the cost of making soon covers any extra outlay on
the cost of the kilns. The wall of the kiln is carried up nearly straight
for 6 feet, when it is drawn in, so as to become bluntly conical. Upon the
top a plate of iron is fastened in the manner of the keystone of an arch,
and bands of iron are passed round the kiln and drawn tight with screw
bolts and nuts to strengthen it. Double doors of sheet-iron are made at
the bottom and near the tops, by which it is either filled or emptied, and
a few air-holes (B), which may be stopped with loose bricks, left in the
bottom. The second figure shows a kiln of another shape made to burn 3,000
bushels of charcoal, or about 80 cords of wood. The shape is a
parallelogram, having an arched roof, and it is strengthened by a
framework of timber 10 inches square. As the pressure of the gas is
sometimes very great, the walls must be built a brick and a half thick to
prevent their bursting. The usual size is 16 feet wide and high, and 40
feet in length, outside measure. The time occupied in filling, burning,
and emptying a small cone is about three weeks, and four weeks is required
for the larger ones.--_The Gardeners' Chronicle._

ENTRANCE, TIDDINGTON HOUSE, OXON.

Our illustration is a view of the entrance facade to Tiddington House,
Oxfordshire, the residence of the Rev. Joshua Bennett. The house is an old
building of the Georgian period, and though originally plain and
unpretentious, its bold coved cornices under the eaves, its rubbed and
shaped arches, moulded strings, and thick sash bars, made it of
considerable interest to the admirers of the "Queen Anne" school of
architecture, and led to the adoption of that style in the alterations and
additions made last year, of which the work shown in our illustration
formed a small part. Between the "entrance facade" and the wall of the
house there is a space of some twenty feet in length, which is inclosed by
a substantially built conservatory-like erection of Queen Anne design,
forming an outer hall.
