ferent, although loosely considered the same--with linseed oil, a
yellow soap and some other ingredients not essential to be considered
here. Carbon black of high quality is decidedly a blue-black . Lamp
Black often has a brownish tinge, yet a carton of commercial Lamp

Black which I used in painting a machine in my experimental shop,
by mixing linseed oil and turpentine with it a couple of years ago
yielded a color which I have just now compared with Ridgway's charts
and which is his Dark Greenish Blue-Green (Plate XLVIII). A high grade

Bone Black also has a bluish tinge, so that it easily possible that
and in the birds' eyes

outcry arose from the Spotted Towhees, who have now brought some of
their third brood into the glade, presumably to feed them more readily
from the soft food dish which they are now using with the thrashers.
Roughly the western half of the glade is covered with a dense growth
of shrubs, and the western half of this again consists of an almost
impenetrable mass of "sticky monkey" which has lodged and is now a twisted
