The scarlet berries are borne in the ) S2reatest profusion, and, ripening at Genus The West American Scientist. 70 Christmas lime, are extensively used in decorating. The berries are said to have formed an important article of food with the Indians, and school chil- dren frequently eat them: but, so far as known, they are not otherwise ulil- ized. They are not unpleasant to tle palate, having a healthy, bitterish by- taste. The toyon is more useful as a hedge plant, doubtless, than for iis fruit. It ranks high as an ornament | evergreen, the dark foliage forming a beautiful setting for the panicles of white flowers.
