near the top, and is approached by a narrow arched gallery, neatly 

 made of slender sticks resting along a horizontal branch, and about 

 fourteen inches long. This peculiar entrance, no doubt, prevents the

 dozen of these enormous structures, but they were all met with before 

 or after the laying season, so that I did not see the eggs.
