“You have been having a vacation, and now you will have to get back to work,” said Captain Smith. “We are observing the fire of the coast defense guns this morning. Bruce will take the first shoot and Finch, you take the second one. Sergeant Breene can use the radio, but you had better give him your sensings of the positions of the shots with reference to the target before he sends them down. You can get some idea as to the distance the shot falls from the target by the length of the cable between the target and the tug. You will shove off in half an hour. Your plane is having a new engine installed so that you will have to use Batten’s.”
