west, and thereafter the rock cleared away outwardly , until the 

 end of the nest, when the cutting was made inwardly from the 

 starting point toward the gate. The character of the architecture 

 is the same throughout the entire nest, so that the following views 

 will suffice to typify all the interior. The figures PI. YI, fig. 35, 

 and PL Y, figs. 16, 17, give views of vertical and horizontal sec- 

 tions made from the gate (southeast), the l)ottom of the section 

 being twenty-one inches below the surface and the distance of the 

 furthest point from the gate twenty-three and one-half inches. 

 Fig. .3.5, PL YI, is a front view of galleries looking south, and 

 exhibits a surface about seventeen inches in length by seven in 

 height.^ The main series of galleries within this area are accu- 

 rately shown, but the connecting vertical galleries were broken 

 away in the excavation, and are not figured. 



Fig. 16 is a vertical section showing the southwest and south- 

 east sides of the excavation at the same point as the preceding 

 figure, part of which is included in this view.^ There are here 

 shown the general tendency of the galleries (^, ^, g) toward stories, 

 arranged one above another ; the relative position of the honey- 

 rooms (R, R), and the relation of the series to the large honey- 

 rooms, C, D, E, shown fully at fig. 17. 



The broken lines, c I d, and e h k, show a series of rooms, 

 some of which were occupied by larvae and some by honej-bearers. 

 The large rooms, C D E, Fig. 17, belong to the lowest series, and 

 are figured and described as fairly typical of all the honey-rooms 

 and other chambers. They were carefully uncovered by chisel 

 and knife, and after being sketched, a plaster cast was taken of 

 them, which is preserved in my collection.'' These rooms were of

 specimens of the architecture, which were carefully packed in Vjoxes and 

 committed to the Express Company at Colorado Springs. The company 

 received a heavy bill for transfjortation, and delivered my beautiful and
