The road most of the way is reasonably good, partly block pavement, and partly ordinary country road in good condition. The run can easily be made in two hours by a moderately good rider; in three hours by any one who is able to ride twenty-five miles. If the rider has time it is well worth while to do this ride in the morning, and spend the afternoon at Wheeling, or running out here and there in the vicinity of that town—to Deerfield, for example, and back. Or it is quite possible to make the next stage of the journey to Waukesha in the afternoon, and this will be given in the coming week.

MYSTERY OF SILVER PRINTING—(Continued).
Chemists have proved that no substance is sensitive to light when perfectly pure and kept by itself in a dry place. If silver chloride is placed in a glass tube, the air exhausted, and the tube hermetically sealed, it may be exposed to sunlight, and will remain unchanged in color.
The action of light on the silver chloride is to separate the chlorine from the silver, but there must be some substance with which the chlorine will combine, or the light will not decompose the chloride. (Decompose is to separate the parts composing a compound body.)
