Teni’s eyes opened wide with wonder. He had never seen a storeroom so well filled. There were piles and piles of skin boxes filled with powdered buffalo’s meat. There were large baskets filled with grain and beans.

In one corner was a box of wheat, and hanging from the pegs in the wall were the skin clothes and skin leggings ready for winter’s wear.

The boys climbed up some of the pegs and looked over the wall into the large reservoir.

There was only a little water in it, because it had not rained for many months.

One of the stone jars on the wall had some water in it, and Teni took a long drink.

Then they crept carefully along the wall till they came to a part of the cliff which hung over the reservoir.

The boys stood here a few moments and looked down at the water.

“This reservoir is nearly empty,” said Teni.
