 digs and heaves with its mandibles. But let 

 a less crumbling support come to its assist- 

 ance; and pilgrimages of some length are 

 not beyond its powers. 



I reared my guests in a box divided into 

 compartments by means of paper partitions. 

 Each space, representing about the capacity 

 of a Tachytes-cell, received its layer of sand, 

 its pile of Mantes and its larva. And more 

 than one disturbance arose in this refectory, 

 where I had reckoned upon keeping the 

 banqueters isolated one from the other, each
