Beardslee of New York City.When this device suffered from technical limitations, in the autumn of 1862 he advertised in the "Army and Navy Official Gazette" for trained telegraphers.The War Department informed Myer that his actions were "irregular and improper" and he was removed as chief signal officer on November 10, 1863.
