"But he ought to have been sent to the police station long before this," Hilda said tearfully.

"Of course he ought, if all people possessed common-sense; unfortunately, they don't. I expect that at the present moment he is eating bread and jam, or something of that sort in the house of some kind-hearted old lady who has taken him in, and the idea of informing the police has never occurred to her for a moment, and, unfortunately, may not occur for some little time. However, if you will give me the details of his dress, I will go at once with it to the printer's and get two or three hundred notices struck off and sent round, to be placed in tradesmen's windows and stuck up on walls, saying that whoever will bring the child here will be handsomely rewarded. This is sure to fetch him before long."

There was but little sleep that night at General Mathieson's. The master of the house still lay unconscious, and from time to time Dr. Leeds came down to say a few cheering words to the anxious girls. Tom Roberts walked the streets all night with the faint idea of finding the child asleep on a doorstep, and went three times to the police station to ask if there was any news. The first thing in the morning Hilda went with Dr. Leeds to Scotland Yard, and the description of the child was at once sent to every station in London; then she drove by herself to the office of Messrs. Farmer & Pettigrew, and waited there until the latter gentleman arrived. Mr. Pettigrew, who was a very old friend of the family, looked very grave over the news.

"I will not conceal from you, Miss Covington," he said, when she had finished her story, "that the affair looks to me somewhat serious; and I am afraid that you will have to make up your mind that you may not see the little fellow as soon as you expect. Had he been merely lost, you should certainly have heard of him in a few hours after the various and, I may say, judicious steps that you have taken. A child who loses himself in the streets of London is morally certain to come into the hands of the police in a very few hours."

"Then what can have become of him, Mr. Pettigrew?"

"It may be that, as not unfrequently happens, the child has been stolen for the sake of his clothes. In that case he will probably be heard of before very long. Or it may be a case of blackmail. Someone, possibly an acquaintance of one of the servants, may have known that the child, as the grandson and heir of General Mathieson, would be a valuable prize, and that, if he could be carried off, his friends might finally be forced to pay a considerable sum to recover him. I must say that it looks to me like a planned thing. One of the confederates engages the silly woman, his nurse, in a long rambling talk; the other picks the child quietly up or entices him away to the next corner, where he has a cab in waiting, and drives off with him at once. However, in neither case need you fear that the child will come to serious harm. If he has been stolen for the sake of his clothes the woman will very speedily turn him adrift, and he will be brought home to you by the police in rags. If, on the other hand, he has been taken for the purpose of blackmail, you may be sure that he will be well cared for, for he will, in the eyes of those who have taken him, be a most valuable possession. In that case you may not hear from the abductors for some little time. They will know that, as the search continues and no news is obtained, his friends will grow more and more anxious, and more ready to pay handsomely for his return. Of course it is a most annoying and unfortunate business, but I really do not think that you have any occasion to feel anxious about his safety, and it is morally certain that in time you will have him back, safe and sound. Now how is your uncle? I hope that he shows signs of rallying?"

"I am sorry to say there was no sign whatever of his doing so up to eight o'clock this morning, and, indeed, Dr. Pearson told me that he has but little hope of his doing so. He thinks that there has been a slight shock of paralysis. Dr. Leeds speaks a little more hopefully than Dr. Pearson, but that is his way, and I think that he too considers that the end is not far off."

"Your friends, Miss Purcell and her niece, are still with you, I hope?"

"Yes; they will not leave me as long as I am in trouble. I don't know what I should do without them, especially now this new blow has fallen upon me."

"Well, my dear, if you receive any communication respecting this boy send it straight to me. I do not know whether you are aware that you and I have been appointed his guardians?"
