Machinery, cement, cordage, wire ropes, tobacco, leather, &c. are manufactured.
Cordage is manufactured, and there is a trade in cattle and grain.
The cordage works are among the largest in the world, and consume immense quantities of sisal fibre imported from Mexico and manila from the Philippine Islands; binder-twine for binding wheat is one of the principal products.
It is used chiefly in the manufacture of coarse sackcloth, cordage and hammocks, and is exported in large quantities.
Modern Plymouth has varied and important manufactures comprising cordage, woollens, rubber goods, &c. In 1905 the total value of the factory products was $11,115,713, the worsted goods and cordage constituting about nine-tenths of the whole product.
