Indians usually capture this rat for food. About the shores of the 

 Gulf of California I found wood-rats as far out upon the level savannas 

 of that region as there were any mesquites. We obtained specimens 

 as far west as Gardners Laguna, on the Salton River, Lower California. 

 Mesquites were found all along Salton and New rivers, and west of 

 them, at Indian Wells, and in canyons of the Coast Range; but the 

 peculiar type of large spreading mesquite trees of the alluvial soil of 

 the Colorado and Salton rivers does not extend much farther west than 

 Cooks Wells, on the SaltOn River, and the specimens collected at Gard- 

 ners Laguna perhaps mark the western limit of tliis species. Young 

 were found at Seven Wells April 15, and a female taken at Gardners 

 Laguna April 20 contained two small fetuses.
