The laboratory had been built at a later date than the main body of the school, and was reached by a flight of steps from the playground. The room below it was used for coats and hats and other impedimenta the boys might bring with them, each boy having his own peg and place on the shelf for bag or lunch basket. They passed through this room on their way to the laboratory, and so it would be easy for Taylor to take down his coat, and carry it up with him when he went for his practical chemistry lesson, and he did this without any notice being aroused among the other boys.
At twelve o'clock, when school was over, the science master went to the playground to look for Howard, who was eating his sandwiches as he walked up and down. 'You won't be long before you go up to the laboratory, I suppose, Howard?' he said, when he saw the lad.
'No, sir, I'm going in a minute,' said the boy.
'I have left three boys there finishing their work. Just see they leave their things all right, when you go in.'
Horace frequently performed such small services for the science master, and readily promised to do this. But just as Mr. Skeats turned away, Warren came up, and the two stood talking for two or three minutes before Howard went to the laboratory. He ran up the steps, and was surprised to find the door closed, but not locked, as boys usually locked it when they were left to do some work after school hours. When he opened the door, he was struck by the peculiar smell of almonds that pervaded the place. He closed the door, but did not lock it. 'I say, what have you fellows been using?' he said, as he went to the further end of the room. There lay one boy stretched out on the floor near a bench, and close to another lay a second. He tried to rouse the one nearest to him, and then seized him by the legs and dragged him across the room out on to the landing. There he shouted 'Help! help!' and ran back to pull out the others, for he knew the deadly nature of that almond-like smell. He managed to get another to the door, where he would get fresh air, and then returned for the third. He found him lying near 'the stinkery,' and thought he would open that door, for the better ventilation of the outer room; but as he passed his own bench, which stood near, he was overpowered by the fumes pouring out of a flask standing there, from which acid also was boiling over on to the bench and floor. He reeled, and before he could reach the door fell insensible to the ground, one hand falling helplessly into the pool of burning liquid there. But by this time the fresh air had revived the first boy he had dragged out, and he called to a lad in the playground.
'What's the row?' said Warren—for it happened to be that young gentleman. 'Oh, what a stink!' he said the next minute, and putting his head in, he saw Howard and the other lad lying on the floor at the further end of the room. He knew that the fumes were dangerous, and stuffing his pocket-handkerchief into his mouth and up his nostrils, he dashed in and tried to drag both boys at once to the door, but had to drop one just as Mr. Skeats rushed up. He picked up Horace, and carried him down, and then sent for the head master and other lads to carry out those who, although somewhat revived, were still lying on the landing at the top of the steps.
'You must have a doctor, sir,' said Warren, pushing his way through the crowd of boys who had gathered round to know what was the matter.
'Yes, yes,' said the master; and Warren rushed off to the gate and ran hastily down the road. He knew his father was often in the neighbourhood about that time of the day, and, to his great joy, he saw him driving in his gig. The boy ran and shouted, and speedily attracted the doctor's attention when his son shouted, 'Something wrong in the "lab!"'
He ran into the playground, and there half-a-dozen voices called, 'They have carried them all to the master's house.'
Here he found two of the boys well-nigh recovered, but the third one was still unconscious, and Horace seemed even worse. His hand and arms were badly burned with the acid, and there were splashes of it on his face.
