Correspondence. DEPOSIT PLATES. EDITOR ARCHIVES:—Please allow me a word in regard to the electric deposit plate. Mr. E. E. Clark, the owner and manager, has been absent in the West in its interest most of the year, and I have, in his absence, undertaken to look after the making of the plates. For a considerable time past, the plates have been sadly deficient in gold, sometimes not enough being put on to properly vulcanize over. I was unable to account for it, knowing that full quantity of gold was supplied. The secret has been discovered, and the thief lined his pockets instead of coating the plates with gold, and is now in jail awaiting trial for larceny. The plates as now made are all right in every respect, and it is hoped that all its former friends will again come back to its use. Yours, etc., C. S. STOCKTON. Newark, Nov. 17th, '90. Selection.
