About the 20th October having a small quantity of dollars to strike for the Hongkong Bank I tried the effect of the high speed on dollars as I wished to avoid removing the pulleys and also to coin rapidly; the results were satisfactory as the increased impetus certainly produced better coins and the Presses can work continuously without heated bearings.
