They knew that in his stock deals Mr. Fairbanks had a partner. This was Gasper Farrington, a miserly but wealthy magnate of the town.
To their astonishment, this man now came forward with a mortgage on the homestead that Mrs. Fairbanks was positive had been paid off before her husband's death.
Of this, however, she could furnish no written proof. Farrington professed great sympathy for the family of his dead partner, but nevertheless he insisted on collecting the interest on the mortgage.
He seemed very anxious to get the Fairbanks family away from Stanley Junction, and even offered them a bribe to go.
This fact aroused Ralph's suspicions.
He got thinking things over. He suddenly realized what a sacrifice his noble mother was making to keep him at school.
One day he went home with a great resolve in his mind. He announced to his mother that he had decided to put aside boyish sports for hard work.
Ralph was a favorite with local railroaders. The freight yards at Acton caught fire, and Ralph was impressed into temporary service.
The lad's heroic acts won the attention and friendship of the master mechanic of the railroad. Next day Ralph found himself an employee of the Great Northern, as wiper under the foreman of the local roundhouse.
They had offered him a clerical position in the general offices down the line at Springfield, but Ralph declined. He announced his intention of beginning at the very bottom of the railroad ladder and working his way up.
How promptly and triumphantly he reached the first rung, "Ralph of the Roundhouse" has narrated.
It was a hard experience, but he soon won the reputation of turning out the cleanest, brightest locomotives in the service.
Ralph made many friends and some enemies. Among the latter was a dissolute boy named Ike Slump. This young rascal stole nearly a wagon-load of valuable brass fittings from the railroad supply shops, and not a trace of the thief or booty could be discovered by the road detectives.
Ralph had in the meantime befriended and practically adopted a poor waif, named Van Sherwin. The latter had been accidentally struck in the head by a baseball. His reason seemed gone. Ralph's tender-hearted mother cared for him as if he was an only son.
Strange to say, it was through this lone waif whom Ralph had so befriended that the young railroader was led to know a certain Farwell Gibson. This man turned out to be, like Ralph's father, a victim of the wiles of old Gasper Farrington.
Ralph and he got comparing notes. Gibson lived in a lonely stretch of woods. He was day by day doing some grading work, which enabled him to keep alive a legal charter for a cut-off railway line.
He furnished Ralph with the evidence that the mortgage on the Fairbanks home had been paid.
Incidentally, near the woodland seclusion of Farwell Gibson, Ralph ran across a wrecked wagon in a ravine. In this he discovered the metal fittings stolen from the railroad company.
Ike Slump got away, but Ralph secured the plunder. When he returned to Stanley Junction, through a lawyer he made Gasper Farrington acknowledge the mortgage on their home as invalid, much to the chagrin of the old miser.
He told Farrington, too, that he believed he had his father's twenty thousand dollars' worth of railroad bonds hidden away somewhere, and notified him that he should yet try to unravel the mystery surrounding them.
Ralph now reaped the reward of duty well done. Life grew brighter. They had a home, and Mr. Blake, the master mechanic, showed his appreciation of the recovery of the stolen plunder.
Ralph was officially notified that he was promoted to duty at the depot switch tower.
For two days he had been under the skilled tuition of old Jack Knight, learning the ropes. Now, at the noon hour of a bright, balmy autumn day, he entered upon this second grade of service in the employ of the Great Northern.
It was a pleasure to the ardent young railroader to view the panorama of rails and switches in plain view of the switch tower.
It was a fascinating novelty to study old Jack Knight at the levers. One-handed as he was for the occasion, he went through his duties like some skilled master giving an expert exhibition.
The switch levers were numbered up to twenty. In their center was a dial, a foot across. Over its surface ran an indicator, moved by an electric button one mile south, at the main signal tower at the limits of the town.
"Passenger No. 8," "Freight 10," "Express 3," "Special," "Chaser," and half a dozen other regular trains were marked on this dial.
Nearby was a telephone, also connecting with the limits tower. This was in requisition every minute to announce when trains had passed a certain switch, closed again behind them.
A large megaphone hung in readiness near an open window behind the operator, who darted from lever to lever according as he received his orders by 'phone or dial.
For two days, as Ralph had told Mort Bemis, he had been under the skilled tuition of old Jack, learning the switches.
He had gone down the tracks to the limits, foot by foot slowly, twenty times or more that morning, until he had a perfect map in his head of every rail and switch on the roadbeds.
He had familiarized himself with every lever number, and that of every train on the road. He realized that trained eye, ear, and muscle must be ever on the alert, or great loss of life and property might result at any moment.
There was a lull in active duty for the veteran towerman as the noon whistles blew. Knight set the lever for a lazy switch engine taking a siding, sent the noon accommodation on her way, closed the switches after her, and gave attention to Ralph.
"Well, Fairbanks," he said, slipping his coat over one arm and changing his cap, "think you can manage?"
"I can obey orders," answered Ralph.
"That's all you have to do. The limits gives you your cue. Never forget that they are the responsible party. If they say six, make it six, if you see that it's going to bust a train of Pullmans, depot, and all. Obey orders-that's the beginning and end. Number two is: Use your own judgment with chasers and freights when the tracks are full."
Just then the telephone bell rang. Ralph grasped the receiver.
"No. 4, express, backing in," and Ralph repeating it casually for old Jack's benefit, stepped on the long, narrow plank lining the lever platform.
"Three for the yards switch, 7 for the in main, and 4 for the express shed siding," he pronounced.
It took some muscle to pull over the big heavy levers in turn, which were not operated on the new-style compressed air system.
Knight watched him closely, nodding his head in approval as Ralph closed the switches on limits' 'phoning as the express passed certain points. As a locomotive backing three express cars passed the tower and took the sheds tracks, old Jack observed:
"You'll do. I'll drop in later. Your shift runs till 9 P.M. Then Doc Bortree will relieve you."
"All right, Mr. Knight. And thanks for all your trouble in teaching me," said Ralph.
The old towerman disappeared down the trap ladder. Ralph did not sit down. He was alone now, and it would take time and experience to dissipate the natural tension of anxiety he felt.
"It's a big responsibility for a boy," he spoke musingly. "They know their business, though," he went on, "and have confidence in me, it seems. Well, I'll make good, if strict obedience to orders is the keynote."
The ensuing hour was a great strain on Ralph's nerves. It was a critical situation, for at one o'clock it seemed as if every switch engine in the service started up simultaneously.
Three freights and one out and one in passenger complicated the situation. Ralph's eye never left the dial. His ear got trained to catching the slightest click on the telephone.
He felt as flabby as a doormat and was wet with perspiration, as he finally cleared
