As yet, they had been unable to attempt any fancy riding with their ponies, owing to the rugged nature of the country through which they had been journeying.

これまでのところ、旅してきた土地が険しかったため、彼らはポニーで曲乗りを試すことができずにいた。

The guide said that, by making a detour in their journey that day, they would cross table lands several acres in extent and covered with grass.

The boys were now all anxiety to start, while the ponies, after their Sunday rest, were almost as full of life as were their owners.

The little animals were becoming more sure-footed every day, and Ned said that, before the trip was finished, "Jimmie" would be able to walk a slack rope.

An early start was made, so that the party reached the promised table lands shortly before ten o'clock in the forenoon.

早めに出発したので、一行は約束の台地に午前十時少し前に着いた。

A temporary camp was quickly pitched.

仮の野営地がすぐに設けられた。

At their urgent request, Professor Zepplin told the boys to go ahead and enjoy themselves.

少年たちにせがまれて、ツェップリン教授は好きに楽しんでくるがいいと言った。

"I guess I had better go along to see that you do not."

「君たちがそうしないよう見張るために、わしも一緒に行ったほうがよさそうだ」
