 the assignment to fire patrol service 

 over western forests of five squadrons 

 of eighteen planes each. Should this 

 plan or any considerable portion of it 

 meet with approval, the results, in 

 conjunction with those which will be 

 secured by the Canadian Air Board, 

 will go far toward determining both 

 the possibilities and limitations of air- 

 craft in forest work, besides furnish- 

 ing a basis for the determination of 

 costs. The importance of the latter 

 should not be overlooked.
