"Whew!" shrieked the steam-whistle, as the train went crashing towards the station. Bright looked out. The frame and its mail-bags were all right and ready. The net was lowered. Another moment and the mail-bags were swept into the van, while the out-going bags were swept off the projecting arm into the fixed net of the station. The train went through the station with a shriek and a roar. There was a bridge just beyond. The junior sorter forgot to haul up the net, which caught some object close to the bridge--no one knew what or how. No one ever does on such occasions! The result was that the whole apparatus was demolished; the side of the van was torn out, and Mr Bright and the junior sorter, who were leaning against it at the time, were sent, in a shower of woodwork, burst bags, and letters, into the air. The rest of the van did not leave the rails, and the train shot out of sight in a few seconds, like a giant war-rocket, leaving wreck and ruin behind! There are many miraculous escapes in this world. Mr Bright and the junior sorter illustrated this truth by rising unhurt from the debris of their recent labours, and began sadly to collect the scattered mails. These however were not, like their guardians, undamaged. There were several fatal cases, and among these was the Bones epistle. That important document had been caught by a mass of timber and buried beyond recovery in the ballast of the line. But why pursue this painful subject further? It is sufficient to say that although the scattered mails were carefully collected, re-sorted, and, finally, as far as possible, delivered, the letter with which we have specially to do never reached its destination. Indeed, it never more saw the light of day, but remained in the hole where it had been buried, and thus it came to pass that Mr William Stiggs failed to make his appearance on the appointed night of the 15th, and Abel Bones was constrained to venture on his deed of darkness alone. On the appointed night, however, Tottie did not fail to do her best to frustrate her father's plans. After a solemn, and last, consultation with her mother, she left her home with fluttering heart and dry tongue, and made for the General Post-Office. CHAPTER NINETEEN. DEEP-LAID PLANS FOR CHECKMATING MR. BONES. Now it chanced that the Post-Office Message-boys' Literary Association had fixed to hold its first grand soiree on the night of the 15th.
