“Dear Madam,—There is a little girl living in your neighbourhood, in whose father I have a deep interest. I am particularly anxious to give this child, Gertrude Marrot by name, a good plain education. Understanding that your daughter has had considerable experience in teaching the young, and is, or has been, engaged in tuition, I venture to propose that she should undertake the training of this child, who will attend at your daughter’s residence for that purpose at any hours you may deem most suitable. In the belief that your daughter will have no objection to accept of this trust I enclose a cheque for 50 pounds—the first year’s salary—in advance. I am, dear madam, your very obedient servant,

“Samuel Tough.”

Although the above can scarcely be considered a brilliant achievement of Edwin Gurwood, it nevertheless accomplished its purpose; for the letter was, in all respects, so very unlike Captain Lee, that neither Mrs Tipps nor her daughter suspected him for an instant. On the contrary, they took it in good faith. Netta wrote a reply by return of post agreeing to the proposal, and on the day following began her pleasant task, to the inexpressible delight of Gertie, who would joyfully, on any terms whatever, have been Netta’s slave—not to mention pupil.

A considerable time after this happy arrangement had been made, Mrs Durby, in a moment of confidential weakness, related to little Gertie the circumstances attending the loss of the diamond ring. Gertie, on returning home, communicated the matter to Loo, and gave it as her opinion that it was a pity such a valuable ring had been lost.

“Couldn’t father find out about it somehow?” she asked with a hopeful look—hopeful because she believed her father capable of doing anything he chose to set his mind to.

“Perhaps he could, but he won’t be home to-night,” replied Loo, thoughtfully.

“I think Sam Natly could tell us how to find it. Suppose I go and ask him,” said Gertie.

Loo laughed, and said she thought Sam couldn’t help them much. The child was, however, a resolute little thing, and, having taken up the idea, determined to go and see Sam forthwith, as he was on duty not far from John Marrot’s cottage.

Sam had recently been advanced from the position of a porter, to the responsible office of a signalman. The great sin he had committed in going to sleep in a first-class carriage, when unable to keep his eyes open, had been forgiven, partly because it was his first offence, partly because of the good and opportune service he had rendered on the day of the attempted robbery, and partly on account of his being one of the steadiest and most intelligent men on the line. Sam’s wife, under the care of Mrs Tipps and Mrs Durby, had made a marvellous recovery, and Sam’s gratitude knew no bounds. Mrs Tipps happened to refer to him one day when conversing with Captain Lee, and the latter was much pleased to discover that the man in whom Mrs Tipps felt so much interest, was the same man who had come to his help in the hour of his extremity. He therefore made inquiry about him of the station-master at Clatterby. That gentleman said that Sam was a first-rate man, a stout, hard-working, modest fellow, besides being remarkably intelligent, and clear-headed and cool, especially in the midst of danger, as had been exemplified more than once in cases of accident at the station, in addition to which Sam was a confirmed abstainer from strong drink. All these facts were remembered, and when the block system of signalling was introduced on that part of the line Sam was made a signalman.

The scene of his new labours was an elevated box at the side of the line, not far from Gertie’s home. As this box was rather curious we shall describe it. It was a huge square sentry-box, with three of its sides composed of windows; these commanded a view of the line in all directions. On the fourth side of the box hung a time-piece and a framed copy of signal regulations. There was a diminutive stove in one corner, and a chest in another. In front of the box facing the clock were two telegraphic instruments, and a row of eight or ten long iron levers, which very much resembled a row of muskets in a rack. These levers were formidable instruments in aspect and in fact, for they not only cost Sam a pretty strong effort to move them, but they moved points and signals, on the correct and prompt movements of which depended the safety of the line, and the lives of human beings.
