The wood was used by the Indians for bows. The dark red branches are a 

 favorite article among many tribes for the manufacture of baslvets. The fruit 

 is sour and was eaten by the Indians, sometimes after having been preserved 

 by drying. The fruit is often soalied in water with sugar to form a refreshing 

 drinlv.

The leaves were smoked by the Indians of Texas, either alone or mixeil with 

 tobacco. It is probably this species (it may be R. glabra) of which Berlandier 

 writes,* as follows : " The Ayumd abounded everywhere along the road, in the 

 bottoms of the valleys, and along the beds of the arroyos ; it is a small shrub 

 6 to 12 feet high ; its appearance is that of the plants of the family Terebin- 

 thaceae. The inhabitants of Texas call it Ayumd, and the Comanches, who 

 smoke it, know it imder the name of Temaichia. The savages gather its leaves 

 generally in the autumn, these being then red and very sharp ; to preserve them 

 they dry them by the fire or in the sun, and to smoke them they mix them with 

 tobacco. The fruits are arranged in pyramidal racemes, rounded in form, red, 

 oblong, and slightly acid. It is said that in Santa Fe, New Mexico, they make 

 vinegar of the fruits of another species of Ayum6."
