In 1905 Portland was the first manufacturing city of the state, with a factory product valued at $9,132,801 (as against $8,527,649 for Lewiston, which outranked Portland in 1900); here are foundries and machine-shops, planing-mills, car and railway repair shops, packing and canning establishments - probably the first Indian corn canned in the United States was canned near Portland in 1840 - potteries, and factories for making boots, shoes, clothing, matches, screens, sleighs, carriages, cosmetics, &c. Shipbuilding and fishing are important industries.
The coasting trade consists chiefly of imports of coal and provisions, the exports being principally timber for shipbuilding and flint for the Staffordshire potteries.
There are also large potteries, silk-mills, a brewery and a tobacco factory.
It is a poor and crowded district, and a large industrial population is employed in the riverside wharves and in potteries, glassworks and other manufactures.
