at ten cents each when fewer than 50 copies are purchased, but 
when ordered in lots of 50 or more copies, whether of the same 
or of different sheets, the price is six cents each.” 
These maps are published by the United States Geological Sur- 
vey, and orders for them should be sent to the director of that 
bureau at Washington, D.C. The order should be accompanied by 
cash or a post office money order. Each quadrangle has a special 
name by which it must be ordered. A large portion of New York 
State has been covered by such topographic surveys and, in order 
to know how to get the map covering a given region, reference 
should be made to the Index to Atlas Sheets for New York State. 
This index may be procured free of charge by dropping a post 
card to the Director of the United States Geological Survey. 
The value of these maps to teachers of geography and physical 
geography would be difficult to overestimate, and every school 
should have a supply of these maps readily accessible. For the 
teaching of home geography as well as that of other, parts of the 
State, for example, Niagara Falls, the Thousand Islands, New York 
City and vicinity, etc., no other map is comparable because, in addi- 
tion to the ordinary features, the relief (topography) of the land is 
shown in detail. In other states, also, many places of importance 
or geographic interest have been covered by such maps. 
BIBLIOGRAPHY 
This bibliography includes only the bulletins and papers of a 
more general character dealing with the physical features of New 
York State. There is no attempt at completeness. An extended 
list of all State Museum publications is given at the end of this 
bulletin, but many important, though technical or special, publica- 
tions of the State Museum are not named in this chapter. The 
most exhaustive lists of papers dealing with the geology of New 
York, both those issued by the New York State Museum and pub- 
lished elsewhere, are to be found in United States Geological Sur- 
vey Bulletins 127, 188, 189, 301, 372, 409, 444 and 495, covering 
the years 1732 to 1910 inclusive. For still later years other bulle- 
tins will appear. By referring to “New York” in the index, the 
subjects and regions treated may be readily found. Numerous ref- 
erences are also given in Tarr’s Physical Geography of New York 
State. The reader who desires to know what scientific publications 
of the New York survey refer to a given subject or region should 
address the Director of the State Museum, Education Building,
