Similarly, if you ask any of these scientific gentlemen the reason of the forms of hoar-frost on your window-pane, they will tell you they may be all explained by the “theory of congelation.”

Finally; here is the first part of the question, in brief terms for you to think over.

A cubic foot of snow falls on the top of the Alps. It takes, more or less, forty years (if it doesn’t melt) to get to the bottom of them. During that period it has been warmed by forty summers, frozen by forty winters; sunned and shaded,—sopped and dried,—dropped and picked up again,—wasted and supplied,—cracked and mended,—squeezed together and pulled asunder, by every possible variety of temperature and force that wind, weather, and colossal forces of fall and weight, can bring to bear upon it.

How much of it will get to the bottom? With what additions or substitutions of matter, and in what consistence?

NOTES AND CORRESPONDENCE.

I find an excellent illustration of the state of modern roads, ‘not blamed for blood,’ in the following “Month’s List of Killed and Wounded,” from the ‘Pall Mall Gazette’:—

“We have before us a task at once monotonous, painful, and revolting. It is to record, for the benefit of the public, the monthly list of slaughter by rail, for the last four weeks unprecedented in degree and variety. In August there were three ‘accidents,’ so called, for every five days. In the thirty days of September there have been in all thirty-six. We need not explain the dreary monotony of this work. Every newspaper reader understands that for himself. It is also painful, because we are all more or less concerned, either as travellers, shareholders, or workers on railways; and it is grievous to behold enormous sums of money thrown away at random in compensation for loss of life and limb, in making good the damage done to plant and stock, in costly law litigation, and all for the sake of what is called economy. It is, moreover, a just source of indignation to the tax-payer to reflect that he is compelled to contribute to maintain a costly staff of Government inspectors (let alone the salaries of the Board of Trade), and that for any practical result of the investigations and reports of these gentlemen, their scientific knowledge and ‘urgent recommendations,’ they might as well be men living in the moon. It is revolting because it discloses a miserable greed, and an entire callousness of conscience on the part of railway directors, railway companies, and the railway interest alike, and in the Government and Legislature a most unworthy and unwise cowardice. It is true that the situation may be accounted for by the circumstance that there are between one and two hundred railway directors in the House of Commons who uniformly band together, but that explanation does not improve the fact.

Sept. 2.—North-Eastern Railway, near Hartlepool. Passenger train got off the line; three men killed, several injured. Cause, a defective wheel packed with sheet iron. The driver had been recently fined for driving too slowly.

Sept. 5.—Great Western. A goods train ran into a number of beasts, and then came into collision with another goods train.

Sept. 6.—Line from Helensburgh to Glasgow. A third-class carriage got on fire. No communication between passengers and guard. The former got through the windows as best they could, and were found lying about the line, six of them badly injured.

Sept. 8.—A train appeared quite unexpectedly on the line between. Tamworth and Rugby. One woman run over and killed.

Sept. 9.—Cannon Street. Two carriages jumped off the line; traffic much delayed.

Sept. 9.—Near Guildford. A bullock leaped over a low gate on to the line; seven carriages were turned over the embankment and shivered to splinters; three passengers were killed on the spot, suffocated or jammed to death; about fifteen were injured.

Sept. 10.—London and North-Western, at Watford. Passenger train left the rails where the points are placed, and one carriage was overturned; several persons injured, and many severely shaken.

Sept. 10.—Great Northern, at Ardsley. Some empty carriages were put unsecured on an incline, and ran into the Scotch express; three carriages smashed, several passengers injured, and driver, stoker, and guard badly shaken.

Sept. 11.—Great Eastern, near Sawbridgeworth. A goods train, to which was attached a waggon inscribed as defective and marked for repair, was proceeding on the up line; the waggon broke down, and caught a heavy passenger train on the down line: one side of this train was battered to pieces; many passengers severely shaken and cut with broken glass.

Sept. 12.—East Lancashire, near Bury. A collision between two goods trains. Both lines blocked and waggons smashed. One driver was very badly hurt.

Sept. 13.—London, Chatham, and Dover, near Birchington station. Passenger train drove over a number of oxen; engine was thrown off the line; driver terribly bruised; passengers severely shaken. Cause, the animals got loose while being driven over a level crossing, and no danger signals were hoisted.

Sept. 15.—Caledonian line, near Glasgow. Passenger train ran into a mineral train which had been left planted on the line; one woman not expected to survive, thirteen passengers severely injured. Cause, gross negligence.

Same day, and same line.—Caledonian goods train was run into broadside by a North British train; great damage done; the guard was seriously injured. Cause, defective signalling.

Sept. 16.—Near Birmingham. A passenger train, while passing over some points, got partly off the line; no one severely hurt, but all shaken and frightened. Cause, defective working of points.

Sept. 17.—Between Preston and Liverpool, near Houghton. The express train from Blackburn ran into a luggage train which was in course of being shunted, it being perfectly well known that the express was overdue. About twenty passengers were hurt, or severely shaken and alarmed, but no one was actually killed. Cause, gross negligence, want of punctuality, and too much traffic.

Same day.—Great Eastern. Points not being closed, a cattle train left the metal and ploughed up the line, causing much damage and delay in traffic. Cause, negligence.

Same day.—Oxford and Bletchley Railway. Axle-wheel of waggon broke, and with seven trucks left the line. A general smash ensued; broken carriages were strewed all over the line, and a telegraph post was knocked down: blockage for four hours. Cause, defective axle.

Same day.—A goods train from Bolton to Manchester started so laden as to project over the other line for the down traffic. Encountering the express from Manchester near Stone Clough, every passenger carriage was in succession struck and injured. Cause, gross negligence of porters, station-master, and guard of goods train.

“Here, it will be observed, we have already got eighteen catastrophes within seventeen days. On September 18 and 19 there was a lull, followed by an appalling outbreak.
