in battle; but a gnawing insignificant rat may sink a ship, and one contemptible traitor be able to disseminate poison enough to destroy a republic; while the question of whether Bobby does or does not take his top with him to school to-day, may decide whether he does or does not wander off to the neighboring pond to be drowned; and Smith's being seen to step into a billiard-room may decide the question of credit against him in the Bank discount-committee, and send him to the commercial wall, a bankrupt. That glance of unnecessary and unladylike scorn which Lady Flora yesterday cast upon a beggar-woman who accidently brushed against her costly robes on Broadway, may have lost her a rich husband, who would otherwise have been deceived until after marriage, as to her real character; and the involuntary act of courtesy of John Hawkins, stooping down to pick up the dropped umbrella of a common woman with a baby and two bundles, in a passenger-car, may make him a friend for life, worth more than all he has won by twenty-five years of hard-working industry and honesty. In this point of view there are no "little things;" and probably he is best prepared for all the exigencies of coming life, who is ready to be the least surprised at finding a dwarfed shrub growing up from an acorn, and a mighty tree springing from the proverbial "grain of mustard seed." Not to be prolix on this subject--let us remember one capital illustration--that of the clown and his two pieces of fireworks. No matter in what pantomime the scene occurs, as it may do for any. The clown approaches the door of a dealer in fireworks, finds no one on duty in the shop, enters, and comes out laden with pyrotechnic spoils. He takes a small rocket, fires it, and is knocked down, frightened and stunned by the unexpectedly-heavy explosion. But he recovers directly, and determines to try the experiment over again. There is one immense rocket among the collection he has brought out--one almost as long as himself and apparently capable of holding half a barrel of explosive material. He shakes his head knowingly to the audience, indicative of the fact that _this_ is something immense and that he is going to be very careful about it. He sticks it up in the very middle of the stage, secures a light at the end of a long pole, and touches it off with great fear and trembling. The explosion which follows is exactly that of one Chinese fire-cracker; and the comically disappointed face which the clown turns to the audience is precisely the same that each individual of that audience is continually turning to another audience surrounding him, when the great and small rockets of his daily life go off with such disproportionate effect.
