 time we referred to C. latifolium L. gathered on the shores of the Arctic Sea, were in the collection that 

 was lost.

The tawquoy-meen-ahtick of the Crees is a handsome small tree, rising on the sandy plains of the Saskat- 

 chawan to the height of twenty feet, but extending as far north as Great Slave Lake, where it attains the 

 height of five feet only. Its fruit, termed Tawquoymeena, or Choke-cheiTy, is not very edible in a recent 

 state, but when dried and bruised, forms an esteemed addition to pemmican.
