a rifle or the hammer of a revolver, you may not know it but they are different in every case. Even among the same makes they are different, and can be detected.
"The cartridge in either a gun or revolver is struck at a point which is never in the exact centre or edge, as the case may be, but is always the same for the same weapon. Now the end of the hammer when examined with the microscope bears certain irregularities of marking different from those of every other gun and the shell fired in it is impressed with the particular markings of that hammer, just as paper is by type. On making microphotographs of firing pins or hammers, with special reference to the rounded ends and also photographs of the corresponding rounded depressions in the primers fired by them it is forced on any one that cartridges fired by each individual rifle or pistol can positively be identified.
"You will see on the edge of the photographs I have made a rough sketch calling attention to the 'L'-shaped mark which is the chief characteristic of this hammer, although there are other detailed markings which show well under the microscope but not well in a photograph. You will notice that the characters on the firing hammer are reversed on the cartridge in the same way that a metal type and the character printed by it are reversed as regards one another. Again, depressions on the end of the hammer become raised characters on the cartridge, and raised characters on the hammer become depressions on the cartridge.
"Look at some of these old photographs and you will see that they differ from this. They lack the 'L' mark. Some have circles, others a very different series of pits and elevations, a set of characters when examined and measured under the microscope utterly different from those in every other case. Each is unique, in its pits, lines, circles and irregularities. The laws of chance are as much against two of them having the same markings as they are against the thumb prints of two human subjects being identical. The firing-pin theory, which was used in a famous case in Maine, is just as infallible as the finger-print theory. In this case when we find the owner of the gun making an 'L' mark we shall have the murderer."
Something, I could see, was working on O'Connor's mind. "That's all right," he interjected, "but you know in neither case was the victim shot to death. They were asphyxiated."
"I was coming to that," rejoined Craig. "You recall the peculiar marking on the nose of those bullets? They were what is known as narcotic bullets, an invention of a Pittsburg scientist. They have the property of lulling their victims to almost instant slumber. A slight scratch from these sleep-producing bullets is all that is necessary, as it was in the case of the man who spied on the queer doings on Staten Island. The drug, usually morphia, is carried in tiny wells on the cap of the bullet, is absorbed by the system and acts almost instantly."
The door burst open and Walker Curtis strode in excitedly. He seemed surprised to see us all there, hesitated, then motioned to Kennedy that he wished to see him. For a few moments they talked and finally I caught the remark from Kennedy, "But, Mr. Curtis, I must do it. It is the only way."
Curtis gave a resigned nod and Kennedy turned to us. "Gentlemen," he said, "Mr. Curtis in going over the effects of his sister has found a note from Clendenin which mentions another opium joint down in Chinatown. He wished me to investigate privately, but I have told him it would be impossible."
At the mention of a den in the district he was cleaning up O'Connor had pricked up his ears. "Where is it?" he demanded.
Curtis mentioned a number on Dover Street.
"The Amoy restaurant," ejaculated O'Connor, seizing the telephone. A moment later he was arranging with the captain at the Elizabeth Street station for the warrants for an instant raid.
Chapter XII
The “Dope Trust”
As we hurried into Chinatown from Chatham Square we could see that the district was celebrating its holidays with long ropes of firecrackers, and was feasting to reed discords from the pipes of its most famous musicians, and was gay with the hanging out of many sunflags, red with an eighteen-rayed white sun in the blue union. Both the new tong truce and the anniversary were more than cause for rejoicing.
Hurried though it was, the raid on the Hep Sing joint had been carefully prepared by O'Connor. The house we were after was one of the oldest of the rookeries, with a gaudy restaurant on the second floor, a curio shop on the street level, while in the basement all that was visible was a view of a huge and orderly pile of tea chests. A moment before the windows of the dwellings above the restaurant had been full of people. All had faded away even before the axes began to swing on the basement door which had the appearance of a storeroom for the shop above.
The flimsy outside door went down quickly. But it was only a blind. Another door greeted the raiders. The axes swung noisily and the crowbars tore at the fortified, iron-clad, "ice box" door inside. After breaking it down they had to claw their way through another just like it. The thick doors and tea chests piled up showed why no sounds of gambling and other practices ever were heard outside.
Pushing aside a curtain we were in the main room. The scene was one of confusion showing the hasty departure of the occupants.
Kennedy did not stop here. Within was still another room, for smokers, anything but like the fashionable place we had seen uptown. It was low, common, disgusting. The odour everywhere was offensive; everywhere was filth that should naturally breed disease. It was an inferno reeking with unwholesome sweat and still obscured with dense fumes of smoke.
Three tiers of bunks of hardwood were built along the walls. There was no glamour here; all was sordid. Several Chinamen in various stages of dazed indolence were jabbering in incoherent oblivion, a state I suppose of "Oriental calm."
There, in a bunk, lay Clendenin. His slow and uncertain breathing told of his being under the influence of the drug, and he lay on his back beside a "layout" with a half-cooked pill still in the bowl of his pipe.
The question was to wake him up. Craig began slapping him with a wet towel, directing us how to keep him roused. We walked him about, up and down, dazed, less than half sensible, dreaming, muttering, raving.
A hasty exclamation from O'Connor followed as he drew from the scant cushions of the bunk a long-barreled pistol, a .44 such as the tong leaders used, the same make as had shot Bertha Curtis and Nichi. Craig seized it and stuck it into his pocket.
All the gamblers had fled, all except those too drugged to escape. Where they had gone was indicated by a door leading up to the kitchen of the restaurant. Craig did not stop but leaped upstairs and then down again into a little back court by means of a fire-escape. Through a sort of short alley we groped our way, or rather through an intricate maze of alleys and a labyrinth of blind recesses. We were apparently back of a store on Pell Street.
It was the work of only a moment to go through another door and into another room, filled with smoky, dirty, unpleasant, fetid air. This room, too, seemed to be piled with tea chests. Craig opened one. There lay piles and piles of opium tins, a veritable fortune in the drug.
Mysterious pots and pans, strainers, wooden vessels, and testing instruments were about. The odour of opium in the manufacture was unmistakable, for smoking opium is different from the medicinal drug. There it appeared the supplies of thousands of smokers all over the country were stored and prepared. In a corner a mass of the finished product lay weltering in a basin like treacle. In another corner was the apparatus for remaking yen-shee or once-smoked opium. This I felt was at last the home of the "dope trust," as O'Connor had once called it, the secret realm of a real opium king, the American end of the rich Shanghai syndicate.
A door opened and there stood a Chinaman, stoical, secretive, indifferent, with all the Oriental cunning and cruelty hall-marked on his face. Yet there was a fascination and air of Eastern culture about him in spite of that strange and typical Oriental depth of intrigue and cunning that shone through, great characteristics of the East.
No one said a word as Kennedy continued to ransack the place. At last under a rubbish heap he found a revolver wrapped up loosely in an old sweater.
