[D8953ABK], Letter from Walbaum (W.H.) & Co to West Orange Laboratory, June 25th, 1889

Editor's Notes

"Your esteemed favor of the 24th inst. Came duly to hand and in reply we respectfully refer you to our letter of the 10th ult. Which covers largely the information we wish. We would also ask for samples of the ore you have reently tested, that is samples 1st of the Crude Ore before treatment, 2nd concentrates from seperation and 3rd tailings from seperation in order that our principals can obtain sufficient knowledge of the benefit they will derive in treatment of their ores by your method to justify them in the erection of a plant at their mines. As you can see by the date of our first letter to you on this subject there has already been considerable delay in obtaining the information we desire and we would be greatly obliged to you if now after testing the ore in according with your letter of the 11th ult you would put us in a position to communicate with our principals at your earliest possible convenience. We would also like to know the proportional amount of each product of seperation that is in one hundred parts of crude ore what percentage of concentrates and tailings will be obtained."
