This was exactly what they did. In spite of the oppressive heat the two girls worked faithfully piling the rocks around the tent, until they had raised a parapet nearly half its height. They were inspired to take this precaution by the glowering aspect of the sky, which grew more threatening as the afternoon waned.
Finally Orissa wiped the perspiration from her brow and exclaimed: "That'll do, I'm sure, Syb. And now I'm ready for dinner. What's to eat?"
Sybil made a grimace.
"Bananas and jelly," she replied. "Could you conceive a more horrible combination?"
"Meat all gone?"
"We've part of a baked crab; that's all."
"And the lettuce. I shall have crab salad, with bananas for dessert."
"A salad without lemon or vinegar is the limit," declared Sybil. "I shall stick to bananas and jelly."
Their appetites were still good and Orissa really enjoyed her salad, which she seasoned with salt which they had obtained by evaporating seawater. The bananas were getting to be a trifle irksome to the palate, but as food they were nourishing and satisfying. Neither of the castaways grumbled much at the lack of ordinary food, being grateful at heart that they were able to escape starvation.
The storm burst upon them just after dark and its violence increased hour by hour. There was little rain, and no lightning at all, but the wind held high revel and fluttered the canvas of the tent so powerfully that the girls, huddled anxiously in bed, feared the frail shelter would be torn to shreds.
