Threshing machines, with or even without certain adjustments in the arrangement of the teeth in the cylinder and concave, and with extra screens, are now doing the work with much despatch, and with a fair measure of satisfaction. But the opinion is held by competent judges that a machine that would more completely combine the qualities of the thresher and the huller would be still more satisfactory. It is easily ...

... are vertical, and they generally form a ridge parallel to the southern skirts of the Grampians. The superior strata, Nos. 2 and 1, become less and less inclined on descending to the valley of Strathmore, where the strata, having a concave bend, are said by geologists to lie in a "trough" or "basin." Through the centre of this valley runs an imaginary line A, called technically a "synclinal line," where the beds, which are tilted in opposite directions, may be supposed to meet. It is most important for the observer to mark such lines, ...

... instance, I find a slight pinch between the thumb and finger at the end of the tendril of the Cucurbitaceae causes prompt movement, but a pinch excites no movement in Cissus. The cause is that one side alone (the concave) is irritable in the former; whereas both sides are irritable in Cissus, so if you excite at the same time both OPPOSITE sides there is no movement, but by touching with a pencil the two branches of ...

... into the buoyant air I leap Confident and exulting, at a bound Swifter than whirlwinds happily to sweep On fiery wing the reeling world around: Off with my fetters!—who shall hold me back? My path lies there,—the lightning's sudden track O'er the blue concave of the fathomless deep,— O that I thus could conquer space and time, Soaring above ...

... measured from 6 to 10 inches in diameter. Three other rows cross the Costa in the same neighbourhood separated by a few hundred yards and as they lie at right angles to the stream which there forms a concave bend, they appear to converge upon one point. This would be what may roughly be termed an island between the Costa and a large drain where water in ancient times ...

... after the resemblance of open gates. These were made wholly of silver, and polished, and that all over, excepting the bases, which were of brass. Now on each side of the gates there stood three pillars, which were inserted into the concave bases of the gates, and were suited to them; and round them was drawn a curtain of fine linen; but to the gates themselves, which were twenty cubits in extent, and five in height, the curtain was composed ...

... completes the resemblance. The house, the rooms, are almost absolutely the same; there may be changes of detail, but they don't modify the general effect. There are the same precious pictures on the walls of the salon—the same great dusky fresco in the concave ceiling. The daughter is not rich, I suppose, any more than the mother. The furniture is worn and faded, and I was admitted by a solitary servant, who carried a twinkling taper before me up the great ...
