62 The American Geologist. J " ly 1903 - 
Dr. J. P. LesleYj for a long time state geologist of Penn- 
sylvania, died "it June ist. He was born in Philadelphia on 
September 17, [819; was assistant geologist on the first geo- 
logical survej of Pennsylvania, 1839 to 1841 ; was appointed 
pastor of the Congregational church at Milton, Massachusetts, 
in 1847 (which town was his place of residence at his death), 
but he left the ministry in 1850. In 1873 he was elected prof.es- 
sor of geology and mining engineering' in the University of 
Pennsylvania, and in 1874 he was elected state geologist of 
Pennsylvania. Dr. Lesley was a corporate member of the Na- 
tional Academy of Sciences (1864), and in 1884 was presi- 
dent of the American Association for the Advancement of Sci- 
ence. He was one of the original fellows of the Geological 
Society of America. 
United States Geological Survev. A survey of the 
Bradshaw Mountain district of Arizona has been made by 
Messrs. Jaggard a. id Palache, and the results are now being 
prepared for publication (late in 1903) in the form of a folio. 
Investigations of artesian and other underground waters in 
a number of states in the eastern half of the country are to be 
carried on during the present year. In several instances this 
work is done in co-operation with the state surveys or is under- 
taken by local geologists ; for instance in Maine the worv: will 
be conducted by W. S. Bayley, in Vermont by G. H. Perkins, 
in Massachusetts and Rhode Island by W. O. Crosby, in Con- 
necticut by H. E. Gregory, in New York by M. L. Fuller, in 
Georgia by S. W. McCallie, in Alabama by E. A. Smith, in 
Kentucky and Tennessee by L. C. Glenn, in Missouri by E. M. 
Shepard, in Iowa by W. H. Norton, in Minnesota by C. W. 
Hall, in Michigan by A. C. Lane. 
Field Methods in Water Analysis. In the examina- 
tion of the water resources of the United States, one of the 
most important features is the determination of the character of 
ground and surface waters. The essential characteristics of 
waters that are now or that at some time in the future may be 
used for domestic supply or in locomotive boilers are little 
known, except within limited areas. The work involved in a 
chemical survey, however, as it has been carried on in the past, 
is necessarily expensive and exceedingly slow, and there has 
been great need of rapid and practical field methods, whereby 
a large number of analyses can be made at small cost. 
The w r ork of making all the determinations that are usually 
considered necessary in chemical analyses would, in the wide 
area covered by the United States, be so expensive as to be well 
nigh impracticable, but it is reasonable to believe that, out of 
tlie many determinations usually made in such analyses, a few 
important ones can be selected which shall bear such a relation
