r going to bed supperless many times after a hard day's
march, because our rations had been captured and burned. Our wagon
trains were something immense, while the big Bell tents were in use; but
after what were called by the boys 'pup tents,' or 'dog tents,' were
introduced, the wagon trains were cut down at least three-fourths. For
the pup tents we carried upon our backs, and so dispensed with the great
Bell tents that were hauled in wagons. Our trains had been so large and
cumbersome that military movements were inconceivably slow, and the war
could never have been fought to a successful issue by the North on those
lines."

"I suppose, Doctor, that you were in some of the great battles?" asked
Fred.

"Yes, I was in the battles of Chickamauga, Missionary Ridge, through the
Atlantic campaign; then under General Geo. H. Thomas we marched back
into Tennessee, fought a desperate battle at Franklin, and a few weeks
later annihilated the army at Nashville. While we were doing this,
Sherman was making his renowned march to the sea. But I'll spin you some

"I should never tire hearing your war stories," said Fred.

"Yes; and you would be the first one to go to sleep if I should tell you
of the battle of Chickamauga or Missionary Ridge."

This Fred stoutly denied. "All right," said the Doctor. "I'll test you
one of these evenings."

"The sooner the better," replied Fred. "And now let's have some music."

They sang several anthems and choruses, and all retired at an early
hour, except Denison, who stood watch.

CHAPTER IX.

In the Heart of Labrador.

The central room of the cabin was called the 'engine room.' It was
fifteen feet square, with a hole three feet in diameter in one corner,
now securely covered. It was used for lowering or hoisting objects
through while the globe was at anchor. An aluminum frame or cage,
attached to a windlass by a chain of the same material, was used for
this purpose. A powerful coil steel spring operated the windlass. In
each of the other corners of the room were anchors of aluminum, also
attached to windlasses and worked by steel springs. There was a dynamo
that afforded abundance of light for the ship. This, too, was run by
spring power. The rooms of the cabin were brilliantly lighted, and the
spiral stairway, from the foot of the mast which stood upon the center
of the floor of the engine-room, was illuminate
