In Europe the finer needle oils are 

 used as perfumes in soaps. Some are 

 used as inhalations for lung diseases, 

 and as additions to baths and oint- 

 ments in rheumatic afflictions. 



"A chemical analysis is being made 

 ot all our native woods. While mak- 

 ing the analysis of Western larch, it 

 was noticed that there was an unus- 

 ually high percentage of water-soluble 

 material. This was found to be 

 galactin. Nov;, if this material can 

 be converted into a fermentable sugar, 

 which seems probable, Western larch 

 would have a considerable advantage 

 over other woods as a raw material for 

 grain alcohol. 



Replacing Silk Worms 



"Converting the cellulose into a 

 gelatinous material known as viscose 

 opens up still another field of research 

 for the utilization of wood waste, and 

 adds a new line of products running 

 all the way from sausage casings to 

 tapestry. Many of the silk socks, 

 neckties, and fancy braids now on the 

 market .Contain silk made from wood. 

 Probably in time to come the whims 

 of the silk worm will have little con- 

 trol over the silk market conditions. 



"The kraft paper situation has been 

 one of the most interesting commer- 

 cially as well as experimentally, and 

 especially concerns the South. Kraft 

 differs from other papers in that it is 

 stronger, due to less severe action of 

 the chemicals. It is brown, like what 

 we usually think of as wrapping paper. 

 Large quantities of it are used for 

 that purpose, and it is particularly 

 suitable for large envelopes. It is 

 used for book covers, for imitation 

 leather, and for cardboard suitcases, 

 etc. Gummed strips are used in place 

 of string for tying packages. Cut into 

 strips, either with one side gummed 

 and spread with a fine lint or used 

 plain, it is run into a spinning niachine 

 and twisted into threads. This thread 

 is then woven into such products as 

 onion and coffee bags, matting suit- 

 cases and bags, wall covering similar 

 to burlap, furniture resembling reed, 

 coarse mattings, etc. For many 

 years an attempt has been made to 

 produce a paper twine that could re- 



place the binder twines now made from 

 imported fibres. The question be- 

 came more active again with the re- 

 cent shortage of these other fibres on 

 account of conditions to the south of 

 us. A successful paper substitute 

 would provide for the utilization of a 

 large amount of wood waste, and at 

 the same time would build up a home 

 .industry independent of foreign raw 

 materials. Experimental kraft made 

 at the Forest Products Laboratory, 

 using long-leaf pine mill waste, com- 

 pares favorably with the best krafts 

 on the market. 



Lahoraiori} Work Essential 



"We have been as wasteful of wood 

 as we have been of our food. Some of 

 this waste can be avoided by improv- 

 ed methods of manufacture, some of 

 it by manufacture just as left-overs 

 are now being made over in the 

 kitchen, and more can bs converted 

 into products of an entirely different 

 nature. There are instances where 

 these things are already being done. 

 It is a field with wonderful opportuni- 

 ties for the application of scientific 

 methods, and investigations by the 

 Forest Products Laboratory are in- 

 tended to aid such development." 



CUT WILLOW FOR LIMBS 



TORONTO.— By the stroke of the 

 woodman's axe what was at one time 

 a real beauty spot in the north end is 

 fast disappearing from view in what 

 has always been known as "The 

 Willows," situated on the west side of 

 Yonge street in the Mount Pleasant 

 Cemetery hollow. During the past 

 few days workmen have been busy 

 with axe and saw, removing the old 

 willow trees, that formed in the sum- 

 mer time with the stream below a 

 picturesque scene. The trunks and 

 large limbs have been contracted for 

 by the Dominion Artificial Limb Co. 

 for the manufacturing of wooden legs 

 and arms. The management of the 

 company stated yesterday that there 

 was a shortage of willow at present. 

 The limb company turn pratcically 

 the entire output over to the Govern- 

 ment for the disabled soldiers.
