Jacques rose to hand her on board.
"I hope you have enjoyed your row," he said courteously.
"Thanks!" she returned briefly, avoiding his eyes.

"I think it is too hot to enjoy anything to-day." The tea-kettle was singing merrily on the dainty brass spirit-lamp, and she sat down at the table forthwith.
Jacques stood beside her, silent and friendly as a tame mastiff.

Perhaps his presence after what had just passed between herself and Fletcher made her nervous, or perhaps her thoughts were elsewhere and she forgot to be cautious.

Whatever the cause, she took up the kettle carelessly and knocked it against the spirit-lamp with some force.
Jacques swooped forward and steadied it before it could overturn; but the dodging flame caught the girl's muslin sleeve and set it ablaze in an instant.

She uttered a cry and started up with a wild idea of flinging herself into the river, but Jacques was too quick for her.
