Summary. 
The remarks made in summarising the possibilities of Avemrius 
Carbolineum apply with equal force to Jodelite. The price of the 
solution per gallon is somewhat higher than that of Carbolineum oil; 
on the other hand, the amount of oil absorbed is slightly less, thus bring¬ 
ing the cost of treatment to about the same for both solutions. Pro¬ 
posals as to future experiments with Jodelite are made in Chapter IV. 
(6) ATLAS SOLUTION. 
Atlas Solution. 
A compound solution, known as “Atlas/** Preservative “A.” is on the 
market. It is advertised for the protection of timber, eradicating weeds, 
disinfecting drains, etc.; its composition is a secret, protected by the 
Patents Act. That it is poisonous is stated by its Agents, and if applied 
to the skin causes irritation, though only of a temporary nature. 
Method of Treatment. 
The Company in their prospectus give directions as to the method of 
treating timber with this solution. In the case of sleepers the timber 
should be immersed in a 15 to 25 per cent, cold solution for 24 to 36 
hours. When dry, the timber should be covered with a coat of hot 
coal-tar. 
In the case of treating timber in situ, or when used as a weed-killer 
or as a disinfectant, solutions of varying strength are recommended. 
Absorption of the Solution by Indian Timbers. 
To determine the amount of absorption by various Indian timbers, a 
set of experiments similar to those carried out with Avenarius Carboli- 
* The Agents in India for the solution are W. Crowder & Co., Ltd., 37, Apollo 
Street, Bombay, 1, Yansittart Bow, Calcutta, and Nicol Koad, Karachi; and Finlay, 
Fleming & Co., Bangoon. The cost of ,C A” solution Atlas, in 5 gallon iron drums, is 
K16 ; the strength of the solution required is 5 per cent, to 25 per cent, according to 
the density of the timber and the use for which it is intended.
