chemicals are used.

The Superintendent Speaks: 
              "On March 1st (this year) our stocks of 
              Airco Foundation were normal. Twice 
              within the last month our stock of Three- 
              ply has been entirely exhausted, due to 
              the large -number of orders. However, 
              our capacity to refine, sheet and mill 
              foundation in a big way has enabled us 
              to give prompt service on all orders."
