Note the forest fire just commencing, also the facility afforded by aerial photograps in estimating the 

 general forest conditions and relative areas of timber barrens, etc. 



The work commenced on the 17th of 

 May and has been continued regularly 

 to date, the appended table givhig the 

 ainount of work done.

Staking a Mining Claim 

 The longest flight from the base was 

 250 miles out. In the course of the work 

 done above, many things of different 

 sorts were accomplished. A flight of 

 forty-four miles was made to stake out 

 a mining claim. The plane carried four 

 people, two tents, folding canoe, pro- 

 visions and instruments. The party 

 stayed out two nights and much time was 

 saved, as, in the ordinary course of 

 events, it would have taken two days 

 travel each way by canoe, and with the 

 plane it took less than an hour. 



A boundary survey of some limits had 

 to be made and the starting point was 

 (:ifi(icult to locate, as, if all the work were 

 to be done on the ground, 22 miles of 

 chaining through the woods would be 

 necessary to locate an intersection from 

 wjiich to commence. The plane was 

 sent up and the three sides of the tri- 

 angle, necessary to locate the intersec- 

 tion, were photographed in one day and 

 the course the new line would have to 

 follow was also photographed, showing 

 all the lakes, streams and hills which 

 t'le line would cross. 



On two sides of the triangle, where 

 hnes already existed, they were visible 

 in the photographs at numerous places 

 on the ground and could easily be joined 

 up. Thus all of the field work is prac- 

 tically checked up before beginning the 

 work, which can now be planned with 

 great exactness. It is proposed to put 

 provisions on the lakes which the line 

 will cross ahead of the party so that they 

 •vill only have to carry enough to last for
