86 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
The receiver should be supported at the required height by 
timber blocks; and the creosote tank, constructed of wood, should 
be sunk into the ground immediately beneath it (K, Figs. 1 and 2). 
In the tank there should be a coil of 3-inch steam-pipes (L, Figs. 1 
and 2), with inlet and blow-through cocks, to heat the creosote and 
render it quite fluid. 
Mr Robert Melvin, Engineer, Sunnyside Foundry, Alloa, who 
has erected several large creosoting works, states that he could 
supply and erect a small apparatus like that described, including 
receiver and its fittings, air and force pumps, steam coil, and all 
connections fitted up complete, for £280. The purchaser would 
have to cart the apparatus from the nearest railway station to the 
site, provide any unskilled labour that might be required for lifting 
and handling, and supply timber for the supporting blocks and for 
the tank for holding the creosote. The price does not, of course, 
include the cost of any alterations which might be necessary on 
existing engines, or buildings, with which the apparatus may be 
connected. A light wooden shed, for protection from the weather, 
and to enable creosoting to be carried on when outdoor work was 
impossible, would be necessary. 
Should it be impracticable to use power from an existing engine 
to drive the pumps, they could be made direct-acting at a slightly 
increased cost. 
The apparatus described would be capable of creosoting about 
300 cubic feet of timber at each charge, and would require the 
labour of two men, who could easily deal with one charge per day. 
With proper facilities, and additional hands for bringing forward 
and removing the timber, two charges per day could be treated. 
Assuming that only one charge per day was treated, and that 
1 gallon, or 102 lbs., of creosote per cubic foot was used (less than half 
being often sufficient), and taking the cost of creosote at 3d. per gallon, 
and coals at £1 per ton, to cover long railway carriage and cartage, 
then the maximum cost per charge might be stated as follows :— 
300 gallons of creosote, at 3d. per gallon, . £3 15 0 
Coals, say 15 ewts., at 20s. per ton, . ¢ oOid Ouse 
Wages, two men at 3s. 6d. each, : if On iad 
Engine oil and sundries, say. é : Overs a0 
20. OG 
or an expenditure for labour and material of 4d. per cubie foot.
