Howieson insisted that the bottle of milk which bulged from the bag of the younger Dowbiggin contained spirituous liquors, and warned the two juniors to keep clear of him and to resist every temptation to drinking. He also expressed an earnest hope that a rumour flying round the school about tobacco was not true. But the smell on Dowbiggin's clothes was horrid. Cosh was affectionately exhorted to have a tender care of his health and personal appearance, not to bully Lord Kilspindie's gamekeepers, nor to put his foot into a steel trap, nor to meddle with the rabbits, nor to fall into the Tay, but above all things not to tell lies. Thomas John was beset with requests--that he would leave a lock of his hair in case he should not return, that he would mention the name of the pawn-broker from whom he got his clothes, that he would bring home a bouquet of wild flowers for Bulldog, that he would secure a supply of turnips to make lanterns for Halloween, that he would be kind to Mr. Byles and see that he took a rest in his net, that he would be careful to gather up any "h's" Mr. Byles might drop on the road, and that he should not use bad language under any circumstances. "Never mind what those boys say, Thomas," said Mr. Byles, who had come out in time to catch the last exhortation: "it is far better to himprove, I mean cultivate, the mind than to fly kites like a set of children; but we all hope that you will have a nice fly, don't we, boys?" And sarcasm from so feeble a quarter might have provoked a demonstration had not Byles and his flock been blotted out by an amazing circumstance. As the botanists started, Speug, who had maintained an unusual silence all morning, joined the body along with Nestie, and gave Mr. Byles to understand that he also was hungering for scientific research. After their friends had recovered themselves they buzzed round the two, who were following the Dowbiggins with an admirable affectation of sedateness, but received no satisfaction. Speug contented himself with warning off a dozen henchmen who had fallen in by him with the idea of forming a mock procession, and then giving them a wink of extraordinary suggestiveness. But Nestie was more communicative, and explained the situation at length---- "Peter was a b-botanist all the time, but he did not know it; he fairly loves g-geranniums, and is sorry that he wasted his time on k-kites and snowballs. We are going to himprove our m-minds, and we don't want you to trouble us." But this was not knowledge. It remained a mystery, and when Jock and Bauldie tailed off at the bridge, and Speug, halfway across, turned round and winked again, it was with regret that they betook themselves to their kites, and more than once they found themselves casting longing glances to the distant woods, where Speug was now pursuing the study of botany.
