The Hot Springs, six miles away, contain some peculiar organisms, which 

 have not yet been sufficiently examined. 



In the Arroyo Pecos, and elsewhere in the immediate vicinity of the 

 town, IS an immense alluvial deposit of pleistocene age, containing in- 

 numerable remains of mollusca and occasional mammalian fragments. 



Special facilities are offered to students of wild bees (Apoidea), the 

 available collections and literature being very extensive. Facilities are 

 also offered for the study of Coccidae and other groups of insects. Stu- 

 dents should, if possible, bring their own microscopes, slides, forceps and 

 other accessories. — For further information apply to T. D. A. Cocker-
