A sluice box done, it was carried to the spot selected for it and planted firmly, with its lower end in the stream and its upper end elevated from one to two feet. Then the upper end of the stream was run into it by means of a water trough. The box was now ready for use. By shovelling dirt in at the upper end and allowing the water to run through, the dirt was gradually washed down and out at the lower end, leaving the heavy gold to settle to the bottom and pile up along the upper sides of the cleats previously mentioned. At night the water was turned aside and the day's accumulation of gold was scraped away from the cleats.

"We can do a good deal more with the boxes than we can with the pans," said Foster Portney. "And what washing we want to do must be done before cold weather sets in and the gulch freezes up."

It must not be supposed that the slit in the rocks had been forgotten. To the contrary, all hands had often spoken of it, and as soon as the sluice boxes were finished every one in the claim turned to the place. Two sticks of dynamite were placed in the slit and set off, and the rock blown into a thousand fragments.

The blast revealed an opening beneath the slit which was a yard wide and twice as deep. This opening was filled with loose sand and dirt, and at the bottom of all was a thick layer of gold dust, slightly mixed with silver. They scraped the dust up with great care, and found that it would very nearly fill a quart measure. They hunted eagerly for nuggets, but no more could be found, and the quartz rock Earl had hoped for failed to appear.

"Never mind; we can't expect too much luck," said Mr. Portney. "A heap of dust like this is find enough for one day. Let us scrape the hole thoroughly and cart the dirt down to the nearest sluice box." This was done and they examined the vicinity carefully for another slit, but none appeared. This pocket, like that on Prosper Gulch, was now exhausted, and with a sigh Randy and Earl turned away to the regular work of washing for dust. Each had one of the boxes allotted to him, while Foster Portney took the third. Fred occupied his time between the three and in cooking the meals; and thus the balance of the summer slipped by until the day came when Mr. Portney announced that they must begin building a cabin and prepare for the long Alaskan winter which would speedily close in around them.


CHAPTER XXVII.

THE END OF THE SUMMER SEASON.

Mr. Portney and the boys had long since decided where the cabin should be built, up against the side of a cliff, ten feet in height, which overlooked the head of the gulch. All the miners in the locality had agreed that this would be the best spot, and six cabins were to be placed there, for hospitality's sake if for no other reason. Mr. Portney had already ordered the dressed lumber needed from the saw-mill; but as this was costly stuff, and expensive to transport, Earl and Randy had declared their intention to go into the timber back of the cliff and get out whatever of rough wood could be made to do.
