Continuing my descriptive catalogue Of things of most general

other countries in arts of most general utility.
They began this business Of scale-makng twenty

they send numbers to China, Inds, Europe and indeed
wherever American merchant ship goes Year by year the
demand increases compel the house increase their
facilities for supplying them This fact backed by the large
number of premiums they have taken for best articles in their
line, show that the world does not embrace just such another
