time.  The tube emerging a little beyond the mouth of the cylinder, through which the expanding gases are expelled, can be slightly deviated from its axial position in any direction, and thus what little steering is required is easily effected.  The long projecting 40 foot vane or tail which steadies the motion of the whole machine is, in the newest patents, made to assist it in alighting on the slides easily and without jarring.  Such is the splendid apparatus, briefly described, which brings all the ends of the earth together and makes the whole world a public park, the most distant parts of which can be visited and returned from in the course of a day.  Long tedious voyages of a week or a month belong to the forgotten past, for Paris, Calcutta or Hong Kong can be reached in a fraction of the time formerly occupied in going from Toronto to Montreal.  No passenger traffic is ever carried on now in dangerous vessels upon the treacherous ocean, but solely in the safe and comfortable rocket-car through the air a thousand feet or more above the cruel waters.  Steamships, electric ships and sailing vessels are still common round our coasts engaged in transporting heavy freight, but they only cross the ocean to convey some bulky produce which cannot be divided and go by car.

Private vehicles and travelling have also undergone wonderful changes.  The much-abused horse has vanished from cities entirely, and is not permitted to enter them, greatly to the preservation of health and cleanliness.  All our vehicles have the automatic electric attachment and move along briskly through the clean wide streets.  The handsome electric tricycles we are so familiar with, were hardly thought of a hundred years ago; now there are few men who do not possess a single or a double one.

How dismal must night have been in the times when only gas lamps or a few electric lights were used in the streets, although our great-grandfathers appear to have extracted a good deal of merriment from the dimly lighted hours after sundown.  Our domestic lighting is now done almost entirely by electricity, or the brilliant little phosphorescent lamps, gas having long been banished from dwelling-houses; and our method of lighting the streets is a grand advance, indeed, upon the flickering yellow gas lamps of old.  The great glass globes, which we see suspended from the beautiful Gothic metal framework at the intersections of streets, contain a smaller hollow globe, about eighteen inches in diameter, of hard lime, or some other refractory material, which is kept at white heat by a powerful oxyhydrogen flame inside.  In this way our cities are illuminated by a number of miniature suns, making all the principal streets as light by night as by day.
