Once, on a trip up an estero that wound past a little hill, they had noticed a big flat rock that Delbert thought would make a fine hearthstone. They could find other flat rocks, of course, but this one had especially appealed to the boy, because it was much larger and smoother than any other they had seen, and he thought it would be nice to have the hearth of one big stone. Marian thought so, too, but was afraid it was too big for them to manage. However, she finally consented to try it. If they could get it on board the Muggywah at all, they could find some way of getting it off again and up the hill and into place.

After all, thought Marian, if her flock learned to achieve things, to overcome difficulties, to persist in spite of obstacles, was that not of itself a fair education? And to bring that great rock home would certainly be a lesson in achievement.

So they went after it. They took plenty of ropes along and several round pieces of driftwood to serve as rollers under the stone. They found it readily. One side was so flat and smooth that it seemed as if it must some time have been worked upon by human hands; the other was rough and irregular, being much thicker at one end than at the other. It was all Marian and Delbert could do to lift it alone, and even with Jennie’s and Esther’s help it was none too easy. Fortunately it was not far from the water’s edge. They got it on their two largest rollers, and, by smoothing the way and prying the rollers along, they got it down to the Muggywah.

Then it developed that it would be more easily got aboard at low than at high tide. At low tide the Muggywah could be placed under a bank and the big stone swung off on to her; at high tide it would have to be lifted up to get it aboard.

So they made their preparations. They tied the Muggywah fore and aft, and rigged up a tripod to assist in swinging the hearthstone over on to her just where they wanted it. They pushed and pried the rollers, and tugged and twisted till they had the big stone in position on the edge of the bank, and then retired to the shade of a scrubby mesquite to eat their lunch of turnips and carrots and drink Island water from the bottles, while they waited for the tide to go out.

And when the lunch was finished, they sallied forth and hunted for panales, clams, oysters, and, incidentally, arrowheads and more hatchets.

When the Muggywah dropped below the bank, they rallied again to the task in hand. The tripod was a big help; they had the hair rope for that. Carefully they worked. It was not merely the getting of the big stone that Marian had in mind; she wanted to be quite sure no one was going to get hurt in the process.

“Delbert, don’t lift on that till you really strain yourself,” she said. “Davie, you stand by that pole and see that it doesn’t lift up; I don’t want your little fingers mashed under this. Esther, poke that stick under there where Jennie’s fingers are. There, that’s right; that holds it instead. Now, Jennie, you stand there where Delbert is. Delbert, you and I will have to swing round below here now. Davie, hold that pole down tight.”

Davie held valiantly with all his might. There was no danger of that particular pole budging, but Marian wanted him out of the way, and knew that the only way to be sure he would not slip in at the wrong minute, and maybe get a finger jammed before she could help him, was to keep him busy elsewhere.

“There, now, you see, part of the weight comes on the tripod. Carefully now, Esther. Jennie can do that alone now; you jump down and be ready to help here.”
