They were soon in the woods. The streams they met with were turbid, and full to the brim.
"We shall have trouble with this water, Roger," Oswald said, as they waded across one, waist deep. "This is but a little stream, but if there are larger ones, as is like enough, we shall have to swim before we are done. There is one advantage; in such weather as this, even the Welsh will scarce be active."
"They have not got much clothing to wet," Roger said. "Their dress is better suited than ours for such weather."
The way was a rough one. Hills, although of no great height, had to be crossed, and many streams to be waded. Fortunately, they met with few larger than that they had first crossed; for the water from that side of the hills made its way, for the most part, direct into the Severn; while that which came down from the slopes of Plinlimmon, towards the road, fell into a stream; dry in fine weather, but now a raging torrent, which ran past Llandulas and into the Severn, at Llanidloes.
"Do you think that we are going right, Roger?" Oswald said, after they had been walking for six or seven hours; "for, what with these ups and downs, and turnings and windings, there is no saying which is east and which is west. If the sun were shining we should be sure of our direction, but with these dull leaden clouds there is no saying."
"I have no idea, master. If we were out on a moor we should be able to judge, and to make a fairly straight course, keeping the wind and rain on one side of us; but in this thick forest, though most of the leaves have fallen, those that remain on the branches break up the rain, and it seems to come straight down upon us."
Presently they came to another watercourse.
"Why, Roger, the water is going in the other direction!"
"So it is, master. How can that be?"
"It is just possible that we have crossed some dividing point, and the water is making its way towards the south, and will fall into some other river; but I am very much afraid that the real explanation is, that we have entirely lost our way, and are going in the opposite direction to that in which we started. The question is, shall we cross it or shall we follow it down?"
