On Feb. 25th, Mr. Müller gave a farewell address at the Presbyterian Church, and on the 26th we went on board the "City of Bridgetown," an "inland route" river steamer, in which, with 136 other passengers, we sailed (viâ Brunswick and Fernandina) for Jacksonville, in Florida. By the term "inland route," is meant a voyage down the river Savannah, across lakes, estuaries, and along wide streams, but inside the land which forms a boundary to the Atlantic Ocean. Our voyage proved, however, most tedious and intricate; for several times the vessel grounded, and as it was necessary to wait for the tide to rise and set her afloat again, great delay and inconvenience were occasioned; but on the afternoon of the 28th, after steaming through a most tortuous water-course, a perfect labyrinth of winding streams, we got safely into the St. John's river, and in the evening reached Jacksonville, after a voyage of 350 miles, which it took 52 hours and a half to accomplish. We arrived too late, however, for Mr. Müller to preach that evening, though the service had been advertised. He held meetings therefore in this city five times only, all of which were numerously attended; and at Polk's Hall, on Sunday evening, March 3rd, there was a union or mass meeting, where a vast audience assembled, which was said to be the largest congregation ever known in Jacksonville. Here, and in Florida generally, vegetation was most luxuriant; for, as some parts of the coast are only 130 miles from the West Indies, the climate of this State is tropical; and flowers, fruit, and vegetables were in season, that in most other countries can be obtained only in the summer.
