cnced ])ilots arc necessary, and the fact 

 I'lat men have wide experience in flying 

 land machines does not always quahfy 

 them for seaplane work. Only the high- 

 est type of men should he emi)loyed, holh 

 as pilots, mechanics and riggers, as men 

 cf a lower type are likely to have a 

 lower sense of the rcsponsihility and im- 

 ])ortance of their work. Men who are 

 reckless or who drink should never he 

 employed. 



Rigid inspections before flights are 

 absolutely essential and no machine 

 should ever go up if there is the slightest 

 doubt about it being in perfect flying 

 condition. The amounts invested are 

 bjrge and the loss of a machine is a 

 serious matter, ever leaving out of ac- 

 count the risk to the personnel. 



Uses of the Dirigible 

 The development of the "Pony Blimp" 

 or small dirigible, opens up a new line 

 of development which is very promising. 

 With a speed of 45 miles per hour and a 

 wide cruising radius, it uses only three 

 gallons of gas per hour and has a greater 

 carrying capacity than a plane. As it 

 can be stopped in the air at almost any 

 altitude, it offers an ideal means of tim- 

 ber cruising and mapping and for carry- 

 ing fire fighters and equipment and also 

 supplies for survey parties and logging 

 camps. If the ri5,k of fire is not great 

 cmd the cost of plant fo/ charging with 

 gss not too expensive it will be an ideal 

 adjunct to forestry and logging work. 

 It will also do away with, what in the 

 northeastern part of the continent is a 

 ■great drawback to aerial work, the in- 

 iibility to fly in winter. It may be that 

 we shall be able to make flying practical 

 but so far it is out of the question with 

 planes on account of the low tempera- 

 tures and deep snows which we have in 

 eastern Canada. 



I feel that aerial transportation and 

 photography have come to stay and that 

 with careful, well thought-out develop- 

 ment will prove invaluable in the man- 

 ?gement and exploitation of large tim- 

 ber holdings. We are constantly trying 

 to study out new ideas for the planes and 

 the camera and are sure tliat their field 

 of usefullness will become larger and 

 more important. 



Growing Square Trees! 



Cambridge, England. — Tlie Cam- 

 l)ii(lgeshire School of Forestry believes 

 ili;i1 "Ihere is no reason why trees can 

 Ui.t Ije made to grow square and prodi.ce' 

 wood of better quality and in greater 

 ouantity" if the excessive wood produc- 

 tion in certain trees can be controlled. 

 The association believes that this can be 

 done and if so "there will be no more 

 slabs nor wavy planks." 



The lumber trade is not likely to in- 

 vest much in the square tree proposition. 

 Put, if it is a success, there is no reason 

 why some other new things shouldn't be 

 developed. For example, an auger that 

 would bore square holes. — American 

 Liunberinaii. 



Forest Industry in Poland. 



The Polish paper industry consists of 

 great enterprises, with a working capi- 

 tal of 100,000,000 marks. In 1913 there 

 were in Poland nineteen paper factories 

 and 20,000 work-people employed. The 

 produce consists of almost all varieties 

 of paper. 



Galicia is in a much better situation 

 th.an the Kingdom of Poland itself, as 

 she has more woods and quick rivers. 



The Buffalo aNd tpe Timber Tree 



"Not only has the buffalo gone from 

 the prairies but the forests have fast 

 disappeared. With the disappearance of 

 the forests the wild thing that dwelt 

 there have also gone and the amount 

 of moistiu'e in the air and the rainfall 

 has changed. Drainage has added to the 

 change that is so gradually going on that 

 it is not noticed. 



"People have become so used to find- 

 ing their newspaper or their magazine in 

 their homes that they give no thought to 

 tlie possibility of having to do without 

 it. Yet with the going of the forests the 

 basic source of newspapers is disappear- 

 ing. 



"Without pulp wood there can be no 

 papers and reforestation is the only 

 means of meeting the problem yet little 

 ha"? been done toward that end."
