Another trouble connected with tunneling was the number of traitors and
spies among us. There were many--principally among the N'Yaarker crowd
who were always zealous to betray a tunnel, in order to curry favor with
the Rebel officers. Then, again, the Rebels had numbers of their own men

brand him with a great "T," the top part to extend across his forehead
and the stem to run down his nose. Captain Jack got his tattooing kit
ready, and the fellow was thrown upon the ground and held there. The
