This was a slight decrease from the figures fig-ures or 19101.05 per cent in production and 0.91 per cent in value but while the industry wa.s not especially active certain changes, such as the replacement of old mills by a smaller number of larger, modern mills and the establishment establish-ment of mixing plants In commercial centers, should result, according to Mr. Burchard, In the saving of freight charges on finished plasters and enable the products prod-ucts to be sold to the consumer at low rates.
