the old leaves are more or less thickly clothed, especially beneath, with a compact yellowish tomentum, exactly 

 as in onr Europaean A. vulgaris, from which it appears to me not easy to distinguish it. Michaux seems to 

 have included these two and the following species under his A. Cafiadensis, Dr. Richardson observes that 

 " this abounds on the sandy plains of tlie Saskatchawau. Its wood, named by the Crees Meesassquat-ahtick^ 

 is prized for making- arrows and pipe-stems, and is thence termed by the Canadian voyagers bois de fleche. 

 Its berries, about the size of a pea, are the finest fruit in the country, and are nsed by the Croes under the 

 name of Meesasscootoom-meen.a,hoih in a fresh and dried state. They form a pleajjuut addition to Pemiuican, 

 and make excellent pudding, very little inferior to plum-pudding."

 Morrison, — What I here consider to be the Pyrus sanguinea of Pursh, Is principally distinj^uished from our 

 A. Boti-yapinm by its fewer-flowered, much shorter racemes, and the shorter and broader or more ovate petals. 

 The leaves are hairy when young-, as in that species. Pursh describes the fruit as red; Mr. Liudley as 

 blackish-purple.

 Observatory Inlet. Dr. Scouler. — This is a small tree, of which the wood is employed for making Medgea, 

 and is so hard as to be susceptible of a fine polish. The fruit is used as an article of food, and called in the 

 vernacular language of the Chenook tribe, Pow-itch. It flowers in April and May.
