The policeman was a very well-dressed and gentlemanly-looking personage. He was standing, at the time when Mr. George saw him, on the edge of the sidewalk, looking at some beggar boys, who had brooms in their hands, as if they were going to sweep the crossings. The boys, however, when they saw that the policeman was looking at them, seemed alarmed, and one calling to the other, said, "Joey!" and then they both ran away round a corner.

Mr. George advanced to the policeman, and asked him if that building was the Horse Guards. The policeman listened to and answered his question in a very polite and gentlemanly manner. Mr. George made several additional inquiries in respect to the building, and received in reply to them a great deal of useful information. Rollo stood by all the while, listening to the conversation, and observing with the greatest interest the details of the uniform which the policeman wore. He was dressed, Rollo saw, in a suit of dark blue, which fitted his form very nicely. The coat had a standing collar, and was buttoned snugly up to the chin with bright buttons. On the collar was worked the letter and number, A 335, in white braid, which denoted the division that this officer belonged to, and his number in the division. The hat was peculiar, too, being glazed at the top and at the brim, and having an appearance as if covered with cloth at the sides. The figure of the policeman was very erect, and his air and bearing very gentlemanly, and he answered all Mr. George's inquiries in the most affable manner.

Every part of London is provided with policemen of this character, whose business it is to preserve order in the streets, to arrest criminals, to take care of lost children, to guide strangers, and to answer any inquiries that any person may wish to make in respect to the streets, squares, public buildings, and other objects of interest in the metropolis. The whole number of these policemen is very great, there being near six thousand of them in all. They are all young and active men; and in order that they may perform their duties in an efficient manner, they are clothed with a great deal of authority; but they exercise their power with so much gentleness and discretion that they are universal favorites with all the people who traverse the streets, except, perhaps, the beggar boys and vagabonds. They stand in perpetual awe of them.

Each policeman has his own district, which is called his beat; and he walks to and fro in this beat all the time while he is on duty. There is a station near this beat, to which he takes any delinquents or criminals that he may have occasion to arrest, in order that they may be examined, and, if found guilty, sent to prison.

One day Rollo saw a policeman taking a prisoner to the station. It was a boy about thirteen years old. The policeman walked very fast, and the boy ran along by his side. The policeman took hold of the collar of the boy's jacket behind with his hand, and so conducted him along. There was a crowd of young men and boys following, some walking fast and some running, to see what would become of the prisoner.

Rollo was at first inclined to join this party, in order that he might see too; but Mr. George thought it would be better not to do so. Rollo then began to pity the poor prisoner boy very much, in view of the expression of dreadful terror and distress which his countenance had worn when he passed by him, and he was very anxious to know what he had been doing. He accordingly stopped to ask an orange woman, who stood with a basket of oranges near a post at a corner.

"He has been beating and abusing a little boy," said the woman, "and spilling all his milk."

"Come, Rollo," said Mr. George, "we must go along."

Rollo would have liked very much to have inquired further into this transaction; but he relinquished the idea, in compliance with his uncle's wish. He found, however, that his sympathy for the poor prisoner, as is usual in such cases, was very much diminished by knowing the offence of which he had been guilty.

Rollo had an opportunity to experience the advantages of the London system of police three or four days after this, in an emergency, which, as I am now speaking of the policemen, I will mention here. He had been to see the British Museum with his uncle George, and had undertaken to find his way back to the lodgings in Northumberland Court alone, his uncle having had occasion at that time to go in another direction. The distance from the museum to Northumberland Court was only about a mile; but the intervening streets were very short, narrow, and intricate, and were inclined towards each other at all possible angles, so that Rollo very soon lost his way. In fact, he soon became completely turned round; and, instead of going towards Northumberland Court, he went wandering on in exactly a contrary direction. He turned this way and that, and looked at the names of the streets on all the corners, in hopes to find some one he had heard of before. Finally he became completely bewildered.

"I shall have to give it up," said he to himself. "If it was a pleasant day, I could go by the sun; for by keeping to the south I should, sooner or later, come to the river."

Unfortunately for Rollo, as is usually the case in London, the sun was not to be seen. The sky was obscured with an impenetrable veil of smoke and vapor.

"I'll take a cab," said Rollo, "at the first stand, and tell the cabman to drive me to Northumberland Court. He must find where it is the best way he can."

Rollo put his hands in his pockets as he said this, and found, to his consternation, that he had no money. He had left his purse in the pocket of another suit of clothes at home. He immediately decided that he must give up the plan of taking a cab, since he had no money to pay for it. This difficulty, however, was, in fact, by no means insuperable, as he might have taken a cab, and paid the fare when he arrived at his lodgings, by asking the man to wait at the door while he went up to get his purse. He did not, however, think of this plan, but decided at once that he must find some other way of getting home than by taking a cab.

"I will ask a policeman," said he.

So he began to look about for a policeman; and as there are so many thousands of them on duty in London, one can almost always be very readily found; and, when found, he is instantly known by his uniform.

Rollo met the policeman walking towards him on the sidewalk.

"I want to find my way to Northumberland Court," said he. "Will you be good enough to tell me which way to go?"

The policeman looked at Rollo a moment with a kind and friendly expression of countenance.

"Why, it is two miles and a half from here," said he, "at least, and a very difficult way to find. I think you had better take a cab."

"But I have not any money," said Rollo.

The policeman looked at Rollo again with as near an approach to an expression of surprise on his countenance as it is possible for a policeman to manifest, since it is a part of his professional duty never to be surprised at anything or thrown off his guard. Rollo was, however, so well dressed, and was so gentlemanly in his air and bearing, that almost any one would have wondered a little to hear him say that he had no money.

"I accidentally left my money all at home," said Rollo, by way of explanation.

"Very well," said the policeman; "come with me."

So Rollo and the policeman walked along together. As they walked they fell into conversation, and Rollo told the policeman who he was, and how he came to lose his way. The policeman was very much interested when he heard that his young friend was an American; and he asked him a great many questions about New York and Boston. He said he had a brother in Boston, and another in Cincinnati.

After walking the distance of two or three blocks, the policeman said,——

"This is the end of my beat. I must now put you in charge of another officer."

So saying, he made a signal to another policeman, who was on the opposite sidewalk, and then going up to him with Rollo, he said,——

"This young gentleman wishes to go to Northumberland Court. Pass him along. He is from America."

So Rollo walked with the second policeman to the end of his beat, talking with him all the way about America and about what he had seen in London. At the end of the second policeman's beat Rollo was placed in the charge of a third policeman; and thus he was conducted all the way, until he came in sight of Charing Cross by a succession of policemen, without ever making it necessary for any one of them to leave his beat. As soon as Charing Cross came into view, with the tall Nelson monument, in Trafalgar Square, to mark it, Rollo at once knew where he was. So he told the policeman who had him in charge there that he could go the rest of the way alone; and so, thanking him for his kindness and bidding him good by, he ran gayly home.

Thus the policemen are, in many ways, the stranger's friends. They are to be found every where; and they are always ready to render any service which the passenger may require of them. Each one is furnished with a baton, which is his badge of office; a rattle, with which he calls other policemen to his aid when he requires them; a lantern for the night; and an oilskin cape for rainy weather. In winter, too, they have greatcoats, made in a peculiar fashion.

But to return to the Horse Guards. After Mr. George had finished his conversation with the policeman about the Horse Guards, he said to Rollo that he was going over to the other side of the street, in order to get a better view of the building. So he led the way, and Rollo followed him. When they reached the opposite sidewalk, Mr. George took his station on the margin of it, and began to survey the edifice on the opposite side of the street with great apparent interest.

"I don't see any thing very remarkable about it," said Rollo.

"It is the head quarters of the British army," said Mr. George.

"What elegant black horses those troopers are upon!" said Rollo.

"It is the centre of a power," said Mr. George, talking, apparently, to himself, "that is felt in every quarter of the world."

"I should like to have such a uniform as that," said Rollo, "and to be mounted on such a horse; but then, I should rather ride about the city than to stand still all the time in one of those sentry boxes."

"About the town, you mean," said Mr. George.

Rollo here observed that there was an open gateway in front of the Horse Guards, and beyond it an arched passage, leading directly through the centre of the building to some place in the rear of it. There were a great many people coming and going through this passage way; so many, in fact, as to make it evident that it was a public thoroughfare. Rollo asked his uncle George where that passage way led to.

"It leads to the rear of the Horse Guards," said Mr. George, "where there is a great parade ground, and through the parade ground to Hyde Park. I have studied it out on the map."

"Let us go through and see the parade ground," said Rollo.

"No," said Mr. George, "not now. We had better go some morning when the troops are parading there. We must go now and look out our lodgings."

So Mr. George and Rollo walked on, and about half an hour afterwards Mr. George engaged lodgings in a place near the junction of the Strand with Charing Cross, called Northumberland Court.
