The car seen peering out of a breach in the wall of the building in our photo. was loaded with twenty tons of coal, and belonged to the Orange Electric Light and Power Co., of New Jersey. It was given a push by its engine about a quarter of a mile from the incline, which rises steeply from the ground to the first floor of the building seen in our illustration. Apparently the push was too hard, for the truck went away at a tremendous pace, which the brakesman was powerless to moderate, sailed up the incline like a bird, and was brought to a standstill by the brick wall, out of which it "butted" a huge fragment.

The curious markings are always to be observed, to a greater or less extent, upon firing any gun; they are probably caused by the escape of the gases past the "driving-band" at the moment it leaves the muzzle. The "driving-band" is the brass ring on the base of the projectile, which cuts its way through the rifling of the gun, giving the shot the necessary rotary movement. The regularity of each spurt of gas is very singular. We are indebted for the snap-shot to an officer in H. M. Navy. [Illustration] "THE SPITE HOUSE." This odd building stands on the corner of 161st Street and Melrose Avenue, New York City. It is a bit over 4ft. in depth, 17ft. frontage, and one and a-half storeys high, with a basement and sub-basement built under the broad sidewalk, extending to the curb. The house itself is of wood, on a steel frame, and has a slate roof. Its owner is an eccentric tailor, who lives and carries on his trade below the street. The interior consists of a small show-room, a store-room, and spiral iron stairway going down to the "lower regions." The upper storey seems to have been constructed merely as a finishing touch. It is reached by an iron ladder from the store-room. The entire construction, appointments, and fittings are very ingenious, and are all the ideas of the owner. The story of the house is that the original lot was cut away in opening the avenue, save only the few feet now occupied by the building. A controversy arose between the tailor and the owner of the adjoining property regarding the disposal of the small strip, and the tailor becoming enraged because his neighbour would neither sell his property nor pay the price the knight of the shears demanded, built this odd structure out of spite. The photo. was taken just at the completion of the building, and before the street had been fully paved. It shows, however, the dimensions of the building, and also the construction under the street, etc. Photo. sent in by Mr. W. R. Yard, 156, Fifth Avenue, New York City. AN EGG WITH A BOOT-LACE YOLK.
