"That wouldn't do me much good," said Lawrence. "I want to know where some one resides this year."

"It will do a great deal of good," said the other, "for if we know where a person has lived, inquiries can be made there as to where he has gone. Sometimes we go back three or four years, and when we have once found a man's name, we follow him up from place to place until we can give the inquirer his present address. What is the name you wanted, sir? You were looking in the K's."

"Keswick," said Lawrence, "Junius Keswick."

The man ran his finger and his eyes down a column, and remarked: "There is Keswick, but it is Peter, laborer; I suppose that isn't the party."

Lawrence smiled, and shook his head.

"We will take the year before that," said the man with cheerful alacrity, heaving up another volume. "Here's two Keswicks," he said in a moment, "one John, and the other Stephen W. Neither of them right?"

"No," said Lawrence, "my man is Junius, and we need not go any farther back. I am afraid the person I am looking for was only a sojourner in the city, and that his name did not get into the directory. I know that he was here year before last."

"All right, sir," said the other, pushing aside the volume he had been consulting. "We'll find the man for you from the hotel books, and what is more, we can see those two Keswicks that I found last. Perhaps they were relations of his, and he was staying with them. If you put the matter in our hands, we'll give you the address to-morrow night, provided it's an ordinary case. But if he has gone to Australia or Japan, of course, it'll take longer. Is it crime or relationship?"

"Neither," replied Lawrence.

"It is generally one of them," said the man, "and if it's crime we carry it on to a certain point, and then put it into the hands of the detectives, for we've nothing to do with police business, private or otherwise. But if it's relationship, we'll go right through with it to the end. Any kind of information you may want we'll give you here; scientific, biographical, business, healthfulness of localities, genuineness of antiquities, age and standing of individuals, purity of liquors or teas from sample, Bible items localized, china verified; in fact, anything you want to know we can tell you. Of course we don't pretend that we know all these things, but we know the people who do know, or who can find them out. By coming to us, and paying a small sum, the most valuable information, which it would take you years to find out, can be secured with certainty, and generally in a few days. We know what to do, and where to go, and that's the point. If it's a new bug, or a microscope insect we put it into the hands of a man who knows just what high scientific authority to apply to; if it's the middle name of your next door neighbor we'll give it to you from his baptismal record. I'm getting up a pamphlet-circular which will be ready in about a week, and which will fully explain our methods of business, with the charges for the different items, etc."
