Harriet argued. Robina pleaded; but in spite of herself, the girl who was quite straight, who had no crooked thoughts, whose one desire was to do to others as she would be done by, was no match for the girl who was deceitful and intensely selfish. In the end, Robina was forced by her companion to give the promise that she would say nothing until the week was up. Book 2--CHAPTER ELEVEN. ON BOARD THE "SEA-GULL." The next day dawned gloriously, and soon after ten o'clock the entire party were on board the pretty yacht which was known by the name of the "Sea-Gull." She had been hired by Mr Durrant for the occasion, and was as charming a sea home as any girls could live in. The eight girls who now took possession of the pretty little cabins and who ran up and down the "companion" stairs and walked on the deck, and disported themselves so happily with the sea breezes blowing on their cheeks, and the white sails of the yacht fluttering in the breeze had never known a more enjoyable time than that first day on board the "Sea-Gull." The "Sea-Gull," like a large white bird, skimmed lightly over the water. The girls were all excellent sailors. The sky was cloudless. Mr Durrant seemed absolutely to have recovered his serene good humour. Ralph was in the highest spirits, and even the school-mothers were so absorbed in their new surroundings that they had no time for trouble or care. It was after dinner, on the first evening of their sojourn on board the "Sea-Gull" that Mr Durrant, rising from his place at the head of the table, spoke to his little party. "Now, my children," he said, "we have entered on a week which I hope will remain long in the memories of each and all of you--a week which it will be my endeavour to make one of pure and perfect happiness. There is no time like youth for the enjoyment of such. As we get older, we cannot quite get away from our cares, however hard we try to do so; but when we are young, we are meant to be like the young birds and the young lambs and the young puppy dogs and the young kittens--all gaiety and sunshine, and lightness of heart. I have on board this yacht with me, a crew and an excellent sea-worthy captain and a first mate and all the rest, and I also have nine young people who none of them exceed twelve years of age. This expedition is entirely carried out for the sake of one little boy and his eight school-mothers, and I trust, therefore, we shall have a very jolly time. "On the night of our return to Sunshine Lodge, I shall have a very important decision to announce, but in the meantime, my children, let us forget all about it; let us be happy while we may; let us banish dull care; let us be, from the oldest to the youngest, each a truly happy child at heart." "Oh, yes," said Robina's voice.
