A three to five horse power dynamo will operate a big machine, and a you will readily see the cost of separating is a very small item. I think it would enrich your Jones ore are satisfactorily, and would suggest that you make a visit to the Laboratory with me and see the machine in operation.""},{"label":"Author","value":"Birkinbine, John"},{"label":"Recipient","value":"Harden, John H"},{"label":"Mentioned","value":"Edison, Thomas Alva"},{"label":"Date","value":"1888-12-17"},{"label":"Type","value":"Letter"},{"label":"Subject","value":["Dynamos and generators","Ore milling and separation"]},{"label":"Folder/Volume ID","value":"D8845-F"},{"label":"Microfilm ID","value":"123:1101"},{"label":"Document ID","value":"D8845AGY"},{"label":"URL","value":"https://edisondigital.rutgers.edu/document/D8845AGY"},{"label":"Rights","value":"Thomas Edison National Historical Park"},{"label":"Publisher","value":"Thomas A.
