206 TRINIDAD AND TOBAGO BULLETIN. [XVIIL 4. 



The pieces were put out on September 9, 1919, according to species, 

 and in exactly' similar positions, under severe weathering conditions, on 

 a site in the St. Clair Experiment Station kindly lent to the Forest 

 Department by Mr. W. G. Freeman, Director of Agriculture, for the 

 final durability test. 



The experiment is by no means complete, in that slightly modified 

 treatment may be necessary for individual species, nor is it on a com- 

 mercial scale ; but if, as is expected, sufficiently valuable data is 

 obtained, regarding the comparative durability of treated and untreated 

 pieces, to make a larger attempt worth while, it will certainly prove of 

 great benefit to the (>olony, especially as crude oil is obtainable in 

 sufficient quantities in all our accessible forests. 



The thanks of the Forest Department are due to Mr. P. C. Bird, late 

 Manager of the Trinidad United Oilfields Co., Ltd., at Palo Seco, who 

 very kindly and thoroughly carried out the initial stages of the 

 experiment in cutting and treating the timber.
