'Good-night, and thank you for coming to me, my darling boy; only remember'--very gently--'a _pardoned_ fault needn't be a _forgotten_ one, Johnnie.' 'No, mamma.' There was a momentary quiver in the gay, ringing voice, and it was quite enough for the mother. 'That will do; I can trust you not to forget _this_ time, Johnnie,' she said, and with a happy smile she lay down to sleep. [Illustration] CHAPTER III. WHAT SEVEN CAMPBELLS CAN DO. SPITE of obstacles, the labours of the 'Seven Campbells,' as Willie grandly called them, did effect a great improvement in the desert, and the seventh certainly took his share, so far as such a very small man could; for he pulled up a great many weeds with his little fat hands, and brushed down the gravel on the walks with a tooth-brush! The Doctor, seeing his boys were in earnest, lent them his help whenever he could spare time, sent for the remainder of the gravel for them, showed them how to lay it, trimmed the borders, sowed some potatoes, and presented them with four apple-trees, which he planted at four corners of the ground, and called 'Gozmaringa, Geroldinga, Crevedella, and Spirauca,' after the names of some apple-trees that belonged to King Charlemagne. But, spite of his assistance, there was a great deal requiring the boys' exertions; and they worked like Trojans, devoting nearly all their play-hours and pocket-money to this object, and finding in it both interest and amusement. Johnnie had learnt one or two lessons from this undertaking: first, that in working for a good object, it is not only necessary to have a right intention at starting, but that constant pains and perseverance are requisite,--as in the matter of Caesar; secondly, that a privilege earned is sweeter than one bestowed as a favour,--as in the spending of the half-crown, which his own toil had procured; thirdly, that even for a good object we must not use bad or doubtful means,--as in the matter of the gravel; and fourthly, that hard work--digging, or what not--from a right motive, becomes a much greater pleasure than any that can be procured by idleness. And he had found true, too, what his mother had said, that if he would pursue _one_ thing steadily, and make himself do it in spite of disinclination, the determination and energy thus acquired would help him in everything else.
