ASH.--The $3 gold pieces do not command any premium. The dates given are the common dates. M. C. W.--The two stamps are revenue stamps from Bosnia. They cannot be used in payment of postage. Embossing was described in the last number of the Round Table. Stamps vary in value from year to year, and even month to month. Generally there is an increase year by year, but in a few instances they decrease in value. No catalogue can fix prices, and the same issue may be cheap or dear, according to the condition of the individual stamp. PHILATUS. ADVERTISEMENTS. Highest of all in Leavening Power.--Latest U. S.

[Illustration: Copyright, 1895, by Harper & Brothers.] The last stage of the run from New York to Philadelphia is given in this week's map. The distance is thirty-one miles, and the road, good in the main, is greatly helped by being generally a little down grade. On leaving Trenton by Warren Street the rider will soon come to the Delaware River, which he should cross by the Warren Street Bridge. He then runs into Morrisville on the other side. Immediately after crossing, turn left to the Bristol turnpike, and on reaching this turn to the right into it. The run is direct then to Tullytown and thence to Bristol. Between Tullytown and Bristol the run is along the river, and at times the road is quite good, especially if rain has not made the reddish-yellow earth soggy and muddy. For a good deal of the distance from Trenton to Bristol--a distance of nine miles or more--you will do well to take the side path, which here, as elsewhere over such generally level country as New Jersey and this part of Pennsylvania, is likely to be good.
