GLASS.

The materials for making glass are found everywhere. In the United States there is no deficiency of them. The sands and stones called tarso, which include flinty and crystalline substances generally, and the salts of various plants, particularly of the sea-weed kali, or kelp, constitute the essential ingredients. An extraordinary abundance of fuel is a particular advantage enjoyed by this country for such manufactures. They, however, require large capitals, and involve much manual labor.

Different manufactories of glass are now on foot in the United States. The present duty of 12 J% on all imported articles of glass amounts to a considerable encouragement to those manufactories. If anything in addition is judged eligible, the most proper would appear to be a direct bounty on window-glass and black bottles.

The first recommends itself as an object of general convenience; the last adds to that character the circumstance of being an important item in breweries. A complaint is made of great deficiency in this respect.
