White Sand for Glass Making. 



Upon the Maurice river, about three miles below Millville, 

 in Cumberland county, an important locality occurs, which fur- 

 nishes this valuable material in great abundance. This deposit 

 of sand presents a number of layers, more or less approximating 

 to absolute purity ; but previous to its being employed in the glass- 

 house, it is always necessary to submit it to a careful washing, 

 in order to discharge a small quantity of yellowish and slightly 

 ferruginous clay, with which it is intermingled in the bank. 

 After the washing it is a pure transparent quartzose sand, the 

 grains of which are small and of very uniform size. There are 

 five glass-houses in the vicinity of Millville, besides many at a 

 distance, which are supplied with sand from this spot. Numerous 

 other places throughout the very sandy district before us, yield a 

 material equally good, but scarcely any other point yet explored 

 offers the same readiness of access. 



In the neighbourhood of Mount Hope much good sand is 

 found ; it is used at the Windslow and several other glass works. 

 The sand used at the Waterford glass works is procured in the 

 vicinity of that establishment. 



Within two miles of the Brooklin glass works good sand is 

 procured, and is employed both in these and in the Squankum 

 works. 



The neisjhbourhood of Jackson's srlass works furnishes a sand 

 well adapted for the manufacture of both window and bottle 

 glass.
