Side 19 - We consider this the chief cause of the failures. The other causes mentioned have their weight. The process of calico printing by machinery is the last invention, and the crowning one, in the manufacture of cotton. Before the introduction of calico printing, the cotton manufacture in the United States was considered to be too precarious to justify one in an attempt to manufacture the finer fabrics ; but the introduction of calico printing has placed our cotton manufactures on a permanent basis. Our...
Side 155 - ... traveller, about a quarter of an inch in diameter, with a slit for the insertion of the thread, which is wound by the ring travelling around the bobbin, being held in its horizontal plane, during its circuit, by an iron ring loosely embraced by its lower end and fastened upon the traversing rail, being sufficiently large to allow the head of the bobbin, as well as the traveller, to pass through without touching. This plan of spindle may be driven 8,000...
Side 14 - We must now place our manufacturers by the side of the agriculturist. . . . Experience has taught me that manufactures are now as necessary to our independence as to our comfort.
Side 47 - The difference of power required for the dead spindle is probably as 4000 to 4300, or 4400. Calling 4000 dead spindles equal to 4400 throstle spindles, the power required to operate them, together with the necessary preparatory machinery, will be Equal to that of - 44 horses. 144 Looms (at J2 looms to the horse) 12 do.
Side 239 - Bowed Georgia, takes its name from a mode of cleaning cotton long in use. This was performed by means of the bow-string, which being raised by the hand, and suddenly let go, struck upon the cotton with great force, and thereby served both to separate the gins and open the cotton, so as to render it more fit for the processes that follow. But this mode, whatever advantages it might possess in point of quality, has been abandoned for others better adapted for quantity...

Side 48 - At the Hamilton Mills, in Lowell, where the fall of water is only about 12 feet, the same quantity of machinery is operated by using 60 cubic feet of water per second.
Side 47 - Lowdl, (Ms.) 24 cubic feet of water per second, with a fall of 30 feet, has been found sufficient to operate 4000 spindles, with all the preparatory machinery, for spinning cotton yarn, about No. 30, together with the looms necessary for weaving the same. The spindles in use at that place' are all of the sort called "dead spindles,'* requiring rather more power to operate them than the common English throstle spindles alluded to in the above table.
