PATENT SNOW-GOGGLES 367 



We were all greatly pleased with the device for closing 

 them on the plan of a sack. Outside our bags we had 

 a cover of very thin canvas; this was extremely useful, 

 and I would not be without it for anything. In the 

 daytime the sleeping-bag was always well protected by 

 this cover; no snow could get in. At night it was per-

 moisture of the breath. Instead of condensing on the 

 skin and making it wet, this settled on the cover, form-

 lay stretched on the sledge. This cover ought to be of 

 ample size; it is important that it should be rather

 plenty of it round the neck, and thus prevent the 

 breath from penetrating into the bag. We all had 

 double bags an inner and an outer one. The inner one 

 was of calf -skin or thin female reindeer-skin, and quite 

 light; the outer one was of heavy buck reindeer-skin, 

 and weighed about 13 pounds. Both were open at the 

 end, like a sack, and were laced together round the 

 neck. I have always found this pattern the easiest, 

 simplest, most comfortable, and best. We recommend

Novelties in the way of snow-goggles were many. 

 This was, of course, a matter of the greatest import- 

 ance, and required study it was studied, too! The 

 particular problem was to find good goggles without
