UTILIZATION OF CALIFORNIA EUCALYPTS. 11 
BLUE GUM. 
Table 1 gives the results of the tests on blue gum arranged accord- 
ing to locality of growth. The material cut in any one locality is 
designated as a shipment. In the case of shipments 10 and 17, tests 
were made on both green and air-dry material. ‘In the other three 
shipments green material only was tested. At the bottom of Table 
1 all the shipments are combined. In analyzing Table 1 a con- 
siderable variation in the strength values of blue gum grown in 
different localities is noticeable, and also a variation in the strength 
of the wood of trees cut from the same locality (shipments 66 and 84). 
In comparing the results of the tests on the different shipments 
values for green material are used so as to avoid the influence of 
moisture. It has been found that, in the case of small sticks, after 
a condition of about 30 per cent of moisture has been reached a 
further addition of moisture has no influence on the strength.
