He would have objected. She silenced him with a look that acted on his chafed spirit like oil upon a burn. Her kind, almost tender voice and the soft touch of her fingers on his head soothed his anguish and seemed to counteract the poison instilled by Gowan. He began to doubt the puncher and the witness of his own eyes.

When Blake and his wife came to breakfast, Ashton was so cheerful that they hardly noticed the traces of haggardness that yet lingered in his face. Blake at once centered the attention of all by explaining his plans for the exploration of the cañon. In addition to the surveyor’s chain, a hammer, and the rope and spikes,––which were to be used only in making the descent,––he and Ashton were to carry the level and rod and a quantity of food. At the suggestion of Isobel, he agreed to take her father’s revolver and fire it at intervals, on the chance that the watchers above might see the flash of the shots and so be able to follow the progress of the explorers down in the depths.

Genevieve quickly thought out signals to be given in response. If at night, a torch was to be cast down into the chasm; if in the daytime, a white flag, made of a sheet sent by Yuki, was to be waved out over the brink. As the explorers might become confused in the gloom of the cañon bottom, the point of the bend opposite Dry Fork Gulch was to be marked by a beacon fire built on the verge of the cañon wall. 283

Blake had already arranged everything that he and Ashton were to take down with them. Immediately after breakfast the outfit was fastened on the packhorses, together with food, water and blankets for those who were to remain on the heights. The ladies were determined to keep above the explorers at all points where the rim of the cañon could be approached. Gowan was to fetch and carry for them and take the horses down to the pool for water at night.

Within half an hour after breakfast the party was jogging away from camp, fully equipped for the great undertaking. Gowan was afoot. His horse, as well as the regular pack animals, was heavily loaded with stores. He walked with Isobel, who had insisted that Ashton should ride her pony. Blake strode along at his wife’s stirrup, carrying his son in a clasp as tender as it was strong.

The engineer was the only cheerful member of the party. Even Thomas Herbert, that best tempered of babies, was peevish and fretful. He was instinctively reflexing the suppressed nervousness and anxiety of his mother. Gowan and Ashton were as gloomy in look and speech as the shadowy depths of the cañon. Isobel bravely sought to respond to Blake’s confidence in the favorable outcome of the survey; but her smile, like Genevieve’s, was forced and her eyes were troubled.

They reached the point of attack as the rays of the 284 morning sun were beginning to strike down into the side gorge. This was as Blake had planned. He at once began to direct the preparations for the descent, himself doing the lion’s share of the work.

A long detour to a point higher up the ravine offered an easy descent of its bottom to the place where it pitched steeply into the cañon. Blake preferred to take a short cut down the almost vertical side of the gulch. The three pieces of rope, each a hundred feet long, were knotted together and used to lower a grass-padded package containing all the equipment of the explorers except the level. The bundle was lodged on a broad shelf of rock, over two hundred and fifty feet down.

“Our first measurement,” remarked Blake, as he subtracted from three hundred feet the length of the line left above the edge of the cliff. He jotted down the remainder in his notebook, and nodded to Ashton, who, with Gowan and Isobel, was holding the end of the rope. “You see why I had Mr. Gowan bring gloves and chaps and your leggins. We will make the line fast around that rock, and follow our outfit.”

Ashton stared, slack jawed. “Really, you cannot mean––?”
