"And England was no more guilty in this respect than was America, for in the early days of our own country when people were demanding quicker transportation and swifter mail service thousands of noble beasts offered up their last breath in making the required rate of speed."

"I suppose nobody thought about the horses," murmured the boy. "I am sure I didn't."

"If the public thought at all it was too selfish to care, I am afraid, until threatened by the possibility of the total extermination of these creatures," was his father's reply. "This danger, blended with a humane impulse which rose from the gentler-minded portion of the populace, was the decisive factor in urging men to seek out some other method of travel. Then, too, the world was waking up commercially and it was becoming imperative to find better ways for transporting the ever increasing supplies of merchandise. The quick moving of troops from one point to another was also an issue. Although the canals of England enabled the government to carry quite a large body of men, the method was a slow one. In 1806, for instance, it took exactly a week to shift troops from Liverpool to London, a distance of thirty-four miles."

"Why, they could have marched it in less time than that, couldn't they?" questioned Doris derisively.

"Yes, the journey might easily have been made on foot in two days," nodded her father. "But in war time a long march which exhausts the soldiers is frequently an unwise policy, for the men are in no condition when they arrive to go into immediate action, as reënforcements often must."

"I see," answered Doris.

"When the Liverpool and Manchester Railroad was opened in 1830 this thirty-four miles was covered in two hours," continued Mr. Tolman. "Of course the quick transportation of troops was then, as now, of very vital importance. We have had plenty of illustrations of that in our recent war against Germany. Frequently the fate of a battle has hung on large reënforcements being speedily dispatched to a weak point in the line. Moreover, by means of the railroads, vast quantities of food, ammunition and supplies of all sorts can constantly be sent forward to the men in action. During the late war our American engineers laid miles and miles of track under fire, thereby keeping open the route to the front so that there was no danger of the fighters being cut off and left unequipped. It was a service for which they, as well as our nation, won the highest praise. And not only was there a constant flow of supplies but it was by means of these railroads that hospital trains were enabled to carry to dressing stations far behind the lines thousands of wounded men whose lives might otherwise have been lost."

"I suppose the slightly wounded could be made more comfortable in this way, too," Mrs. Tolman suggested.

"Yes, indeed," was the reply. "Not only were the men better cared for in the roomier hospitals behind the lines, but as there was more space there the peril from contagion, always a menace when large numbers of sick are packed closely together, was greatly lessened; for there is nothing army doctors dread so much as an epidemic of disease when there is not enough room to isolate the patients."

"When did England adopt railroads in place of stagecoaches, Dad?" asked Doris presently.
