194 The American Geologist. March, 1903. 
again, to supplement the studies which lie made last summer 
on Martinique and St. Vincent. Dr. Hovey left New York 
by the steamer "Caribee" of the Quebec line on February 
4th, and will remain in the Windward and Leeward islands 
two months or more. After studying the changes which have 
taken place on Martinique and St. Vincent as a result of the 
great eruptions which have occurred since last July, he will 
visit all the other important volcanic islands of the chain to 
photograph their craters, solfataras and boiling lakes, with the 
idea of making his final report upon the eruption of 1902 in 
the West Indies comprehend the entire series of Caribbean 
volcanoes. He will make collections of volcanic rocks and 
other materials for the Museum. 
A New Division of the United States Geological 
Survey. A new division, to be known as the division of hy- 
drology, has recently been organized in the hydrographic 
branch of the United States Geological Survey. The work of 
this division will include the gathering and filing of well re- 
cords of all kinds, the study of artesian and other problems 
relating to underground waters, and the investigation of the 
stratigraphy of the water-bearing and associated rocks. In 
addition to the gathering of statistics relating to the flow, 
cost, etc., of the wells, it is hoped in the future to give espec- 
ial attention to the geologic features which govern or which 
are related in any way to the supply of water. 
The division will be subdivided into two sections, the 
eastern and the western, the first embracing the Gulf and 
Mississippi River states and the states of the east, and the 
second embracing the remaining ("reclamation") states and 
territories, or those having public lands. The charge of each 
section has been assigned to a geologist, the western section to 
Mr. N. H. Darton, and the eastern to Mr. M. L. Fuller. The 
office details are in charge of Mr. Fuller. 
The sections will be still further subdivided so that each 
state or group of adjacent states shall constitute a district 
in which the work of collecting data and of investigating the 
problems relating to underground water will be in charge of a 
geologist employed for the purpose. 
In the western section it is expected that the study of the 
geologic structure will be followed by the sinking of wells by 
the Survey, the aim being to test such of the arid or semi- 
arid regions as appear to present conditions favorable for ar- 
tesian water, with a view to their ultimate development for 
agricultural purposes.
