There are two sorts of growlers. There is the man who honestly attacks what is really wrong for the sake of making it right, and there is the man who instinctively grumbles at everything for the mere sake of growling. The former class is as useful as the latter is tiresome, and if we must growl, by all means let us find out some real grievance to attack. Grumbling is a habit that grows quickly and with very little encouragement, and those who go in for it must make up their minds to have to do with very few friends. For who would consent to be the friend of a growler? It would be as bad as becoming the servant of a man who kept an electrical machine--he would always be trying it on you! And he must be content also to find that very few people sympathise with him. For when a man is a confirmed grumbler at everything, no one afflicts himself much about his lamentations, but puts it all down to his infirmity. "Poor fellow, his digestion isn't good, or his liver's out of order!" they will say, and think no more about it. Growler of our school was an able fellow in his way; and successful, too, but he wasn't liked. Some were afraid of him, some detested him, and most cared very little about him. I don't suppose he will ever do much good in the world, for this reason--his influence is so small. One would like to know if he is really as unhappy as he would make every one believe. I have a notion he is not, but is the victim of a habit which he has allowed to grow on him till it is past shaking off. Moral, boys: When you catch yourselves grumbling, make sure the grievance is a real one. If it is, don't be content with grumbling, but follow it up till the wrong is put right. But if you find yourself growling merely because it sounds a fine thing to do, then let growl number one be not only the first but the last performance of the kind; and no one then will be able to growl at you. CHAPTER EIGHTEEN. THE BULLY. There are bullies and bullies. There is the big brother, for instance, who considers it as much part of his duty to administer an occasional cuff to his youthful relative, as he does to stroke his own chin for the first sign of a beard, or to wear his tall hat on Sundays. That is not the sort of bullying any one complains of. Pretty sort of fellows some of us would have turned out if we hadn't come in for a little wholesome knocking about in our day! What's the use of big brothers, we should like to know, if it's not to chastise youngsters! and what are younger brothers made for, if they are not to be occasionally "whopped!"
