To quickly assess the difficulty of the text, read a short excerpt:
The great requisite in reeling is evenness and equality 69 in the threads. After the cocoons by reeling have been converted into raw silk, that silk, before it can be used in the manufactory of fine stuffs, must undergo the oper- ation of throwsting, that is to say twisting, which is done by means of a machine called a throwing or throwsting mill, and the mechanics who perform that work are called silk throwsters. There are several of them already in the United States, chiefly from England, but... they have as yet been mostly employed in throwsting foreign silk, imported chiefly from China. * The operation of throwsting is the test of the good or bad reeling of raw silk. If it be entan- gled, or not sufficiently freed f*om its gum, the threads break in the preparatory operation of winding, and that occasions much loss. If the threads are not equal, that is to say, if there is not in each thread as nearly as possible the same number of fibres, as the twisting is done by machinery which works by an equal regular motion, the force which will only twist the strong parts of the thread will break the weak ones, and that with the loss by winding, produces what is called waste.
