rather widely apart, like straight pillars ranged along the 

 sides of the valley, but, afterwards, more closely together, 

 and in a different form — ^namely, that of gigantic cande- 

 labra, of six-and-thirty feet high, which had taken root 

 among stones and in clefts of the rocks, and rose in 

 solitary state at various points. 



" This Cereus giganteus, the queen of the cactus tribe, is 

 known in California and New Mexico imder the name of 

 Petahaya. The missionaries who visited the coimtry be- 

 tween the Colorado and the Gila, more than a hundred 

 years ago, speak of the fruit of the Petahaya, and 

 of the natives of the country using it for food ; and they 

 also mention a remarkable tree that had branches, but no 

 leaves, though it reached the height of sixty feet, and was 

 of considerable girth The wildest and most in- 

 hospitable regions appear to be the peculiar home of this 

 plant, and its fleshy shoots will strike root, and grow to a 

 surprising size, in chasms in heaps of stones, where the 

 closest examination can scarcely discover a particle of 

 vegetable soiL Its form is various, and mostly depen-

 immense club standing upright in the ground, and of 

 double the circumference of the lower part at the top. 

 This form is very striking, while the plant is still only
