In spite of precautions this fact became public and provoked the formidable riot styled "The battle of the umbrellas" that broke out the next day.
The Pennsylvania railway has repair shops here, and among Columbia's manufactures are silk goods, embroidery and laces, iron and steel pipe, engines, laundry machinery, brushes, stoves, iron toys, umbrellas, flour, lumber and wagons; the city is also a busy shipping and trading centre.
There are manufactures of woollen yarn, tobacco, biscuits, umbrellas and printers' ink, and a lively trade is carried on in wax, honey, wool and timber.
The prosperity of the town is largely due to the great slate-quarries of the vicinity, but the distillation of liqueurs from fruit, cable, rope and thread-making, and the manufacture of boots and shoes, umbrellas and parasols are leading industries.
In 1905 the principal products were umbrellas and canes (valued at $2,782,879), cigars and cigarettes ($1,951,971), and foundry and machine-shop products ($1,036,526).
