HIS PART IN THE CIVIL WAR 153 



pair, 'A' (in a diagram enclosed, which showed the exact 

 location of the various mines). 



"Lieutenant Davidson, who with the Teaser and her 

 crew has assisted me with a most hearty good will, has 

 dragged for the tanks without success. They rest on 

 the bottom. Could they be found, it was my intention 

 to raise the four, examine them, and, if found in good 

 order, place them below the range, T. 



''Lieutenant William L. Maury, assisted by Acting 

 Master W. F. Carter and R. Rollins, was charged with 

 the duty of proving the tanks and packing them in casks. 

 There are eleven others, each containing 70 pounds of 

 powder. When tested in the barrels and found ready 

 for use, they will be held in reserve in case of accident to 

 those already down. A larger number was not prepared, 

 for the want of powder. There are a quantity of ad- 

 mirable insulated wire, a number of shells for anchors or 

 torpedoes, and a sufficient quantity of chains for the 

 wires remaining. They will be put in the navy store for 

 safe-keeping. The galvanic batteries; viz., 21 WoUas- 

 tons and 1 Cruikshank, the latter loaned by Dr. Maupin 

 of the University of Virginia, with spare acids, sulphuric 

 and nitric, are at Chapin's Bluff in charge of Acting 

 Master Cheeney. He has also in jugs a sufficient 

 quantity mixed to work the batteries, and ready to be 

 poured in for use. 



"It is proper that I should mention to the Department 

 in terms of commendation the ready and valuable assist- 

 ance afforded by Dr. Morris, president telegraph com- 

 pany, and his assistant, especially by Mr. Goldwell. 

 My duties in connection with these batteries being thus 

 closed, I have the honor to await your further orders".
