 sustenance, and the vital fluids circulated through them. Egypt is the land of hoar antiquity; but what are the wonders of the mummy-case to this? The trees look as if they had fallen down, and been turned to stone on the ground where they grew; they look 'like to a forest felled by mighty winds;' they bear no marks of rolling or abrasion, such as that by which flints themselves are rounded. Yet all is sea-sand and shells everywhere; there is nothing to sustain vegetation; and whether the theory that they belong to an age previous to that of the rock in which they are occasionally imbedded, be adopted or not, it is clear that, subsequent to their assumption of their present form and condition, the ground on which they now repose sunk beneath, and rose again far above, the surface of the sea.

It is singular, considering the extent of area, and the diversity of positions in the world over which silicified trees are found exposed above ground, that so little has been written on the subject. In Trinidad, in the West Indies, they are abundant; and they prevail over a vast expanse of surface on the seaboard of New Holland. They abound on the Coromandel coast near Madras; and in Scinde are found from Sukkur to Kurrachee, on salt desert sand, resting on nummulite limestone, exactly as in Egypt.

It has been already stated that our party arrived at Cairo on the morning of the 23d of December. Only a few hours is allowed, and every one should make his arrangements without unnecessary delay. Having arranged at the Transit Office to get all luggage, a small bag excepted, sent forward, and secured his place, the traveler may be considered ready to start. The conveyance to Suez is by vans, which start in detachments at specified hours. In hot weather, it is preferable to start from Cairo in the afternoon, so as to travel all night. By this plan he arrives at the centre sleeping-station in the morning, and after a few hours' repose, he can again proceed, so as to reach Suez early in the following morning. Some go on direct; others stop.

The distance from Cairo to Suez is eighty-five or eighty-six miles; and as the line of route is without any towns or villages, station-houses have been erected for the accommodation of travelers, and for changing of horses. There are altogether seven station-houses, of which No. 4 from Cairo is the most commodious. Refreshments are furnished at three of the stations, and they are usually of the most sumptuous kind. The vans are of different sizes. For the greater part they are strong clumsy machines, open all around, tolerably stuffed, but without springs—merely suspended on leathern straps. They have two wheels about five feet in diameter; that is, one-third larger than those of a common carriage. They are drawn by four horses, two being in shafts, and two before them in traces. They are, in general, not over-well trained, tempered, or conditioned; but really, on the whole, get on wonderfully well. The plan of the drivers generally is to urge them a good gallop for a mile or so, and then allow them a few minutes to rest. Including twelve hours' repose by the way, the journey from Cairo to Suez is performed in thirty-two to thirty-six hours.

There is but little of the Suez desert covered with drift sand; it consists mainly of hard gravel, with a vast abundance of loose stones in all directions. The vans seldom adhere very regularly to any particular track, and the jolting is occasionally dreadful. In the direction of Suez, as
