Geographical Conditions of Manufacture 239 tana, and Leadville, Colorado. At important quarries like those at Quincy in Massachusetts and Barre in Vermont, many men are en- gaged in chipping the huge rough blocks of granite and marble into symmetrical forms for buildings or monuments. Near the forests one is likely to come upon sawmills, wood- pulp mills, and possibly woodworking and furniture factories. Near southern pine forests the turpentine industry and charcoal burning are usually found. The raw materials from mines, quarries, and forests are almost all bulky. If rough blocks of granite, unsmelted zinc or lead ores, or undressed logs were shipped long distances, large sums would have to be paid for freight on worthless material which is thrown away in the processes of manufacturing. Hence bulky as well as perishable raw materials tend to cause manufacturing to be located close to their place of origin. How transportation facilities favor the location of manufacturing industries. Aside from energetic people, transportation probably does more than any other one factor to determine the location of manufacturing industries. A great city like New York, Chicago, or London is the most inviting place for many industries, not only be- cause the dense population furnishes a large market which can be reached with little transportation, but because there are good facilities for shipping to more distant points. Moreover, such facilities do much to determine how rapidly a city grows. For example, in 1790 New York with 33,000 people was only six times as large as New London, Connecticut, which had 5,150, and seven times as large as New Haven, which had 4,500. Today New London is only four times as populous as it was in 1790, New Haven has increased thirty-fold, and New York one hundred and eighty fold. New London has a fairly good harbor, but its communications inland are poor because the country is hilly. New Haven has a poor, shallow harbor, but the valley lead- ing northward has made the city an important railroad center. New York not only has a superb harbor, but lies at the end of a remarkable valley affording an outlet from the rich interior of a great country. When industries began to grow, New York attracted the manufacturer because there he could so easily obtain his raw materials and ship his products to other places. The establishment of each industry made the city more inviting for others, because the market and labor supply were correspondingly enlarged, and the facilities for transportation improved. Today the goods manufactured in New York and its immediate vicinity amount to an eighth of all the goods made in the United States.
