COLLECTION SECOND, 1844. 
Mr. Lindheimer's Collection of 1844, was made between 
the Brazos near San Felipe, and the Colorado River, in the 
neighborhood of Cat Spring of Mill Creek, the settlement of 
Industry, and thence westward towards the Colorado, and 
along its bottom lands. The prairies are partly of a light and 
even sterile sandy soil, and partly of a stiff clayey soil. The 
bottom lands consist of a stiff black soil, Near Industry, and 
on the Colorado, rocks of a secondary sandstone (probably a 
subcretaceous formation) appear, on which several species of 
Cactus are found. In the prairies ant-hills are not uncom- 
mon, and on old and deserted ones a rich harvest of peculiar 
plants may be made. The numbers run on consecutively 
from the end of the former year's collection. Additional 
` Specimens of the following plants of that collection, gathered 
again in. 1844, are distributed to subscribers (without being
