Prospecting From Aloft. 



As illustrative of the interest which 

 is being taken in the ])lan of the 

 Department, Hon. Mr. PattuUo, 

 stated tha; on his recent trip to the 

 N)rth, he met many prospectors 

 who advocated such a plan in con- 

 nection wi'ih prospecting for minerals. 

 They pointed out that undoubtedly 

 in the near future, in view of the 

 vast strides being made in aviation 

 in commercial pursuits, it would be 

 feasible to use Hying machines in 

 reaching inaccessible spots at present 

 lacking other means of ingress and 

 egress. The department was build- 

 ing its hopes upon using such mach- 

 ines in topographical and surveying 

 work, and in connection with the 

 prosecution of the investigations of 

 the water branch. The commercial 

 possibilities of flying machines, the 

 Minister said, have no limit. 



The machine, the government ar- 

 ranged to secure, is what is known 

 as a flying boat as distinguished 

 from a sea-plane equipped with pon- 

 toons. Flying men who have had 

 active experience with air machines 

 claim that the flying boat is not a 

 satisfactory type, in fact, they say 

 for use in this province, where moun- 

 tain ranges exist and the difTiculties 

 of landing are thereby increased 

 owing to the limited space within 

 which to do so, the type of boat 

 which met with the mishap yester- 

 day is not as satisfactory as the sea- 

 plane type now in use in the naval 

 air service overseas. 



A local Hying man who has seen 

 extensive service overseas in the 

 seaplane service in England, and who 

 is experienced with the best types of 

 machines used for water service, 

 stated yesterday that the flying boat 

 design of the Vancouver machine has 

 the engine behind the head of the 

 pilot, and such an arrangement is 

 not as well adapted for flying condi- 

 tions as the tractor machine with 

 pontoons, such as are the British 

 naval machines. The latter have 



the engine in front, and while the 

 range of vision is therefore, some- 

 what circumscribed, on the other 

 hand, they possess a better driving 

 angle, that is, they give a greater 

 distance within which the machine 

 may descend. In the boat at Van- 

 couver the angle at which it can 

 be brought down is steeper and in a 

 mountainous country that is an unsat- 

 isfactory matter and renders opera- 

 tion less safe for the pilot. 



BY-PRODUCTS AND VELVET 



The Hercules Powder Co. obtained 

 a great contract for explosives pro- 

 vided they bought no acetone, which 

 is scarce and needed for munitions. 

 Under intense research they found 

 they could make it by fermenting 

 kelp. In February, 1916, they broke 

 ground, and by the fall of that year 

 had their $5,000,000 plant in full 

 operation. Besides acetone the kelp 

 yields potassium chloride and new 

 solvents greatly needed in industry. 

 It 16 a great thing to have by-pro- 

 ucts useful, and if they are not, to 

 make them so. — From the Little Jour- 

 nal. 



WHY DOES SAWDUST SINK? 



From American Lumberman 

 Can you explain why the sawdust 

 even of the lighter woods always 

 seems to be heavier than water? 



Even the lightest of known woods 

 is actually heavier than water and 

 floats only because of the air con- 

 tained in its cells. The actual wood 

 structure of all woods, exclusive of 

 the air in the cells, does not varj- 

 greatly in specific gravity. Sawdust 

 is in such form that the air in the 

 air cells is easily lost by replacement 

 with water and when tliis occurs the 

 sawdust sinks. — Editor. 



From Saint John West, N.B. 



"Your publication is an excellent 

 on'i^ and is getting better all the time. 

 Iwish it were more extensively read 

 as I am sure it would prove an educa- 

 tive force much needed in this part 

 of the country at least. Wishing 

 you every success in your grand 

 undertaking." E.R.WT.
