locomotives can be completed per day. During the World War the 
shipyards became temporarily the most enormous in the whole world. 
Philadelphia is also a great center for textiles, such as rugs, carpets, 
underwear, stockings, and cotton and woolen goods. 
The Central New York Manufacturing District 
The Central New York district of intensive manufacturing owes 
its location chiefly to the busy trade route from Albany to Buffalo. 
Although the district is nearly as long as the North Atlantic district, 
its width is limited, for it is scarcely more than a single string of cities. 
The industries of the cities. The cities of this district fall into three 
groups whose location, like that of most cities, depends largely on con- 
ditions of transportation. 
At the eastern end Albany, Schenectady, Troy, Gloversville, and 
Johnstown form a peculiarly specialized little group. Troy is en- 
gaged mainly in making collars and cuffs, simply because that business 
happened to get started there. Gloversville and Johnstown are de- 
voted almost exclusively to glove-making because some Scotch glove- 
makers settled there more than a century ago. They made such good 
gloves and were so progressive in adopting the sewing machine and 
the factory system that these two small cities still make more than 
half the gloves produced in the whole country. Schenectady is not 
quite so specialized, but is known chiefly for its great electrical fac- 
tory and locomotive works. 
A little farther west, Utica has important cotton and woolen mills, 
while Syracuse specializes in automobiles and typewriters. These 
two cities and their smaller neighbors form a group in which transpor- 
tation by water is of no importance. 
Still farther west the third group of the Central New York district 
comprises the lake cities of Rochester and Buffalo, together with 
Niagara Falls. Rochester has made a great reputation for its cameras, 
photographic materials, optical instruments, and thermometers. It 
is a city where a large part of the work is of an unusually skilled type. 
Buffalo has taken advantage of the great quantities of raw materials 
which come to it because it is the eastern terminus of a large 
part of the Great Lakes transportation. Hence it converts wheat 
and meat into finished products, and is a great center for the larger 
kinds of iron and steel work. The splendid supply of hydroelectric 
power from Niagara Falls is a wonderful advantage to Buffalo and 
to the city of Niagara Falls, which has the same kind of industries as 
Buffalo.
