THE CUSTER STEEL CALK MANUFACTURING CO.
This institution for the manufacture of steel heel and toe calks for horse shoes is now in full operation. It is wonderful to see the little machine cutting the calks from the hard, cold steel so rapidly. With this one little machine, calks can be cut at a rate of three tons per day, at a liberal estimate for stoppages, and when run at this rate the expense of the steel used will not be less than $400 per day. It will be seen therefore that it will require some money to run this little enterprise. To feed and attend the machine and run the engine requires the labor of three men. There is a constant demand for toe and heel calks and it is expected that ready sale will be found for all that can be cut. Success to the enterprise and to all manufacturing enterprises that may be attempted in Monroe.
