The Doctor was upon his favorite theme--the propagandism of the peculiar system of medicine of which he was so faithful and successful a practitioner--and they had left the city far behind them, when he again paid attention to the rapidly changing scenery below. The wind had increased to a strong gale, and they were crossing the full length of Pennsylvania at astounding speed. They passed over the mountain ranges of the eastern part of the state, with as little concern or thought as if they had been level plain or water. So greatly had their speed accelerated, that by six o'clock the smoke of the great city was discernible immediately before them. The beautiful Hudson looked like a silver ribbon trending away to the north. New York bay with its shipping from all quarters of the earth, Liberty Lighting the World, the suspension bridge, and the tall buildings of the city, were all distinctly seen by the voyagers at a great distance. The booming of cannon announced to our friends that they had been sighted by those upon the lookout for them. A few moments later they had crossed the river and were skimming over the housetops, looking for an anchorage. "There is Central Park. We shall pass over the south end of it. That is the place for us to drop anchor," said the Professor. "All right, Professor. Stand by boys! Let them go!" cried the Doctor. Down to the earth went two anchors. They almost immediately caught in the strong limbs of the shade trees and Silver Cloud was again safely anchored. It was well that this immense park had chanced to be their stopping place, for the people were wild with excitement, and poured into it like a mighty flood.

The whole party came down, two by two, the fastenings of the globe were made doubly secure, a posse of policemen put in charge of it, and then they submitted themselves to the committee of reception appointed by the mayor. Carriages awaited them, and they were conveyed to a hotel as rapidly as the densely crowded streets would permit. No conqueror ever received a more tremendous ovation! Frequently the carriages were brought to a dead standstill, and only the most strenuous efforts of scores of policemen could make a passage for them. But finally their enthusiasm broke through all barriers. The horses were taken from the vehicles, and hundreds of friendly hands grasped the ropes attached to the ends of the tongues, and then better progress was made. The Doctor bore his honors with gentle dignity, taking off his hat, and bowing frequently to the right and left to his excited and enthusiastic countrymen who thus delighted to do him honor. If Mrs. Jones' eyes filled with tears of pride and delight as she witnessed this outpouring of the hearts of the people to the man whom she loved above anything upon earth, surely no one will censure her for that. The travelers had met with some hearty
