The Annandale (Minn.) Brick & Tile company has been formed with $10,000 capital, by A. M. Ridgway, L. R. Williams, W. D. McDonald, John H. Burt and C. F. Zimmerman. (Clay Record, Clay Record Publishing Company, Chicago, IL, March 15, 1905, Volume XXVI, Number 5, Page 43)
At Annandale in the western part of the county, the Annandale Brick and Tile Company have built a plant on the Soo Line a mile east of town to use a deposit of laminated clay known to cover several acres, with a thickness of at least 15 feet. The clay where used is found to contain sufficient sand, so this sandy part of the deposit remains untouched. In working and burning qualities, the clay seems to be excellent, but some difficulty has been encountered at the plant in getting the clay to dry without cracking.
