CHANGE OF SEASONS AT SEA.

One of the pleasant things about this voyage is, the frequent change of seasons. Leaving New York late in October we were in a few days in the warm region of the Gulf; then came spring and summer in the tropics, then fall and winter with severe blasts round the Horn. To-day, Jan. 6th, spring seems to have dawned. By Jan. 20th, we shall have premonitions of summer heat. I took my old seat on the house under the mizzenmast, a mild air about me yet strong enough to bear the ship along at the rate of eight or nine knots, the sky clear, the water smooth, the horizon distinct, everything indicating our approach to the tropics.
