At times he went so far as to occupy the hanging nest (not shown in the sketch) from which he could com- mand all approaches to the shelf and, at the same time, exclude T from that place of retirement as well. (There are perches, not shown but so disposed as to give ready access to the shelf). This kept up until long after their usual bed-time, and although it seemed good-natured enough and may have been play, I decided to put up a temporary partition at the middle point of shelf A.
