Two lilies there are that, escaping from gardens, in many places have become half wild the brick-red, black-spotted tiger lily with recurved flowerets, after the shape of the Japanese roseum, rubrum, and album, being also a native of Japan and China, and the tawny orange day lily, that is found in masses about old cellars and waysides, with its tubular flowers, held on leafless stems, springing from a matted bed of leaves.
Not to mention its catacombs, which are a separate cellar, not to mention the inextricable trellis-work of gas pipes, without reckoning the vast tubular system for the distribution of fresh water which ends in the pillar fountains, the sewers alone form a tremendous, shadowy net-work under the two banks; a labyrinth which has its slope for its guiding thread.
A. In a flue boiler this cannot be done, but in a tubular boiler it is an advantage that there should be a division between the tubes pertaining to each furnace, so that the smoke of each furnace may be kept apart from the smoke of the furnace adjoining it until the smoke of both enters the chimney, as by this arrangement a furnace only will be rendered inoperative in cleaning the fires instead of a boiler, and the tubes belonging to one furnace may be swept if necessary at sea without interfering injuriously with the action of the rest.
Returning to Hatras Station on the same day, we again took the train, and this time did not leave it until we had crossed the great tubular bridge over the Jumna and come to a standstill in the station at Delhi.
After the linnæa and the arbutus, the prettiest sweet-scented flowering vine our woods hold is the common mitchella vine, called squaw-berry and partridge-berry. It blooms in June, and its twin flowers, light cream-color, velvety, tubular, exhale a most agreeable fragrance. Our flora is much more rich in orchids than the European, and many of ours are fragrant.
Roebling's Niagara Railroad Suspension-Bridge cost four hundred thousand dollars, while a boiler-plate iron bridge upon the tubular system would cost for the same span about four million dollars, even if it were practicable to raise a tubular bridge in one piece over Niagara River at the site of the Suspension Bridge.
As fast as wooden bridges decay, they should be replaced with iron; and if the piers and abutments require it, as is too often the case, they should be rebuilt in a substantial manner. The tubular iron bridge we do not recommend, on account of its excessive cost.
On November 28, while giving the motor a run indoors, we thought we again saw something wrong with one of the propeller shafts. On stopping the motor we discovered that one of the tubular shafts had cracked! Immediate preparation was made for returning to Dayton to build another set of shafts.
In the “Planet” engine, delivered upon the line immediately subsequent to the public opening, all the improvements which had up to that time been contrived by him and his son were introduced in combination—the blast-pipe, the tubular boiler, horizontal cylinders inside the smoke-box, the cranked axle, and the fire-box firmly fixed to the boiler.
The steam-valve is a packed slide with but little lap, and the expansion-valve is an adjustable slide working on the back of the steam-valve. The boilers are of the vertical water-tube type, with the tubes above the furnaces, and are supplied with fresh water by tubular surface-condensers, which, together with the air-pumps, are placed opposite the cylinders.
