Tipps, who was a very simple matter-of-fact man in some ways, looked puzzled.

“Why, how will the sending of a new porter to the station throw light on the matter?”

“You shall know in the course of time, Mr Tipps,” replied the superintendent. “We have wonderful ways of finding out things here.”

“Indeed you have,” said Tipps; “and, by the way, that reminds me that they have some wonderful ways of finding out things on the Continent as well as here. I have just heard of a clever thing done by a German professor. It seems that on one of the lines—I forget which—a large box full of silver-plate was despatched. It had a long way to go, and before reaching its destination the plate was stolen, and the box filled up with sand. On this being discovered, of course every sort of investigation was set on foot, but without success. At last the thing came to the ears of a professor of chemistry—or the police went to him, I don’t know which—and it occurred to him that he might get a clue to the thieves by means of the sand in the box. You see the great difficulty the police had, was to ascertain at which of the innumerable stations on the long line, it was likely that the theft had taken place. The professor ordered samples of the sand at all the stations on the line to be sent to him. These he analysed and examined with the microscope, and found that one of the samples was precisely similar in all respects to the sand in the box. The attention of the police was at once concentrated on the station from which that sand had been gathered, and in a short time the guilty parties were discovered and the theft brought home to them. Now, wasn’t that clever?”

“Very good, very good, indeed,” said Mr Sharp, approvingly, “and rather peculiar. I had a somewhat peculiar case myself last week. You know some time ago there was a quantity of cloth stolen on this line, for which, by the way, we had to pay full compensation. Well, I could not get any clue to the thieves, but at last I thought of a plan. I got some patterns of the cloth from the party that lost it, and sent one of these to every station on the line where it was likely to have been stolen. Just the other day I got a telegram from Croon station stating that a man had been seen going about in a new suit exactly the same as the pattern. Off I went immediately, pounced on the man, taxed him with the theft, and found the remainder of the cloth in his house.”

“Capital,” exclaimed Tipps, “that was smartly managed. And, by the way, wasn’t there something about a case of stealing muffs and boas lately?”

“Yes, and we got hold of that thief too, the day before yesterday,” replied Mr Sharp. “I felt sure, from the way in which the theft was committed, that it must be one of our own men, and so it turned out. He had cut open a bale and taken out several muffs and boas of first-rate sable. One set of ’em he gave to his sweetheart, who was seen wearing them in church on Sunday. I just went to her and said I was going to put a question to her, and warned her to speak the truth, as it would be worse for all parties concerned if she attempted to deceive me. I then asked her if she had got the muff and boa from Jim Croydon, the porter. She blushed scarlet, and admitted it at once, but said, poor thing, that she had no idea they had been stolen, and I believe her. This case occurred just after I had watched the milk-truck the other night for three hours, and found that the thief who had been helping himself to it every morning for some weeks past was the watchman at the station.”

“I fear there are a great many bad fellows amongst us,” said Tipps, shaking his head.

“You are quite mistaken,” replied the superintendent. “There were a good many bad fellows, but I flatter myself that there are very few now in proportion to the number of men on the line. We are constantly winnowing them out, purifying the ore, as it were, so that we are gradually getting rid of all the dross, and leaving nothing but sterling metal on the line. Why, Mr Tipps, you surely don’t expect that railways are to be exempted from black sheep any more than other large companies. Just look at the army and navy, and see what a lot of rascals have to be punished and drummed out of the service every now and then. Same everywhere. Why, when I consider that we employ over twenty thousand men and boys, and that these men and boys are tempted, more almost than any other class of people, by goods lying about constantly in large quantities in the open air, and in all sorts of lonely and out-of-the-way places, my surprise is that our bad men are so few. No doubt we shall always have one or two prowling about, and may occasionally alight on a nest of ’em, but we shall manage to keep ’em down—to winnow them out faster, perhaps, than they come in. I am just going about some little pieces of business of that sort now,” added Mr Sharp; putting on his hat. “Did you wish to speak with me about anything in particular, Mr Tipps?”

“Yes; I wished to ask you if that fat woman, Mrs —, what’s her name?”
