Sept. 28.--South Devon Line, near Plymouth. A luggage train was set on fire, and a van laden with valuable furniture completely consumed. Sept. 30.--The London and Glasgow express came up at full speed near Motherwell Junction, and dashed into a van which was being shunted on the main line; the engine was thrown down an embankment of thirty feet, and but for the accident of the coupling-iron breaking the whole train would have followed it. The fireman was crushed to death, the driver badly injured, and many passengers severely shaken. Cause, criminal recklessness in shunting van when an express is due. Sept. 30.--Great Western. Collision at Uffington between a fish and luggage train; no loss of life, but engine shattered, traffic delayed, and damage done. Cause, negligence. "Besides the above, two express trains had a very narrow escape from serious collision on September 13 and September 26, the one being near Beverley station, and the other on the Great Western, between Oxford and Didcot. Both were within an ace of running into luggage vans which had got off the lines. It will be observed that in this dismal list there is hardly one which can properly be called an accident, i.e., non-essential to the existing condition of things, not to be foreseen or prevented, occurring by chance, which means being caused by our ignorance of laws which we have no means of ascertaining. The reverse is the true state of the case: the real accidents would have been if the catastrophes in question had not occurred." A correspondent, who very properly asks, "Should we not straightway send more missionaries to the Kaffirs?" sends me the following extracts from the papers of this month. I have no time to comment on them. The only conclusion which Mr. Dickens would have drawn from them, would have been that nobody should have been hanged at Kirkdale; the conclusion the public will draw from them will doubtless be, as suggested by my correspondent, the propriety of sending more missionaries to the Kaffirs, with plenty of steam-engines.
