But if a civil engineer is a success he is generally a big one. So is Mr. Jacobs. He is thoroughly well read, though his reading may be somewhat desultory. His splendid memory, assisted by a remarkably quick wit, allows him to feel interested in nearly everything--sociology, literature, art, music, theatre, sport, charity, municipal enterprise. If he is superficial, nobody notices it, for he is much too smart to show it. His general level-headedness makes him an inexhaustible source of admiration to Dr. Ariens, whose peer he is in kindness of heart. His manner is irreproachable; he never loses his temper in discussion, and treats his opponents in such a quiet, courteous way that they are obviously sorry to disagree with him. His business capacities are of the first rank; he makes as much money as he likes, and however crowded his life may be, he always finds time for more work. He is a member of the Town Council and a staunch supporter of Walraven's progressive plans. Walraven has certain misgivings about Jacobs' thoroughness, but he fully realizes his friend's quick grasp of things. He may build bridges, irrigate whole districts, and drain marshes in Holland, open up mines in Spain, build docks in America, or hunt for petroleum in Russia; he is always sure to succeed, and a fair profit for himself, at any rate, is the invariable result of his exertions. He travels a great deal, knows everybody everywhere, and always turns up again in the old haunts, bristling with interesting information, visibly enjoying his busy, full life, and not without a certain vanity, arising from the feeling that his fellow-citizens are rather proud of him.
