Page 34 - RHODIUM.—When rose-wood, the lignum of the Convolvulus scoparius, is distilled, a sweet-smelling oil is procured, resembling in some slight degree the fragrance of the rose, and hence its name. At one time, that is, prior to the cultivation of the rose-leaf geranium, the distillates from rose-wood and from the root of the Genista canariensis (Canary rose-wood), were principally drawn for the adulteration of real otto of roses; but as the geranium oil answers so much better, the oil of rhodium has...

It was found that the same power needed to draw the narrow-tired wagon, with its 2,000-pound load, on a gravel road, would have pulled a load of 2,482 pounds on the wide-tired wagon. The same power, required to draw the...
