CHAPTER XX.
In the favoring current off Cape St.Roque, Brazil--All at sea regarding the Spanish-American war--An exchange of signals with the battle-ship _Oregon_--Off Dreyfus's prison on Devil's Island--Reappearance to the _Spray_ of the north star--The light on Trinidad--A charming introduction to Grenada--Talks to friendly auditors.
On May 10 there was a great change in the condition of the sea; there could be no doubt of my longitude now, if any had before existed in my mind.

Strange and long-forgotten current ripples pattered against the sloop's sides in grateful music; the tune arrested the oar, and I sat quietly listening to it while the _Spray_ kept on her course.

By these current ripples I was assured that she was now off St.Roque and had struck the current which sweeps around that cape.

The trade-winds, we old sailors say, produce this current, which, in its course from this point forward, is governed by the coastline of Brazil, Guiana, Venezuela, and, as some would say, by the Monroe Doctrine.
The trades had been blowing fresh for some time, and the current, now at its height, amounted to forty miles a day.

This, added to the sloop's run by the log, made the handsome day's work of one hundred and eighty miles on several consecutive days, I saw nothing of the coast of Brazil, though I was not many leagues off and was always in the Brazil current.
I did not know that war with Spain had been declared, and that I might be liable, right there, to meet the enemy and be captured.
