Sawdust for Plaster.
There is a great deal of waste sawdust in the United States, and therefore two Western inventors have recently obtained patents for the uso of sawdust instead of, sand in plastering compositions, and this it is conceived may be a matter of considerable importance to owners of saw mills. One patent is for the use of neai-ly equal parts of plaster of Paris or cement and sawdust with the ordinary amount of plastering hair and water. The other calls for the use of about 4^ pounds each of slaked lime and sawdust to 1 pound of plaster of Paris, £ pound glue, and l-16th of a pound of glycerine witli plasterer's hair. Whether or not either of these described plasters would be cheaper than those made in the ordinary way, they would certainly be lighter, and it is believed that they would better adhere to the walls, and be not so i liable to chip, scale, or crack,
