 the nesting-season showed that the nest was composed exclusively of this 

 material, the box being filled to within an inch or two of the level of the en- 

 trance-hole. The male usually left his load at the hole, without entering, and 

 I suppose that the material was put in place by the female inside. 



On April 23, on my return home after a few days' absence, I saw the male

 the light was right, I saw that there was a thin layer of pitch close to the hole. 

 At first this layer was so thin and transparent that it was noticeable only when 

 the sun was shining on it at the right angle, but as the nesting-season advanced 

 more and more pitch was added, so that before long it could be seen easily,
