 their spongy cells, not for a " rainy day," but for a 

 rainless one, for the months when not a drop falls. 

 Here was really a little desert of a few acres' extent, 

 set in the midst of tropical greenness ; for below, the 

 springs kept the vegetation ever luxuriant. 



Woodpeckers and other birds had bored their round 

 holes in the cactus branches, and they doubtless nested
