it in large quantity (as well as from other amyliferous Lichens) ^ 

 by converting the starch into sugar by heat and acids, and the 

 sugar into alcohol by fermentation. f 



Parry points out the scarcity of CI. rangiferina in certain parts 

 of the North-Polar regions, in relation to the requirements of 

 tame Reindeer. " It would be next to impossible to procure there 

 " a supply of provender sufficient even to keep them alive, much 

 " less in tolerable condition, a whole winter " (p. 206). He 

 shipped Reindeer, for sledge-drawing during his expedition, at 

 Hammerfest, taking with him a supply of CI. rangiferina as their 

 only provender (p. 7)4 



Franklin states that his party " used the Reindeer-moss for 

 ** fuel, which afforded us more warmth than we expected " 

 (p. 128).§
