Bruce wondered how it was that his guide should happen to know so much about the fashionable part of the city, even more in fact than he seemed to know about the poorer quarters. It may have been that Chief Trask saw what was uppermost in the boy’s mind, for he said, as if in answer to a question, “I have to know about every part of the city, and it is particularly valuable for me to keep the run of what we call the brown stone district. The men who live here own property all over the city—factories, apartment houses, tenement houses and private dwellings—besides what they live in themselves. If there is ever a riot in the city, and I hope there will never be another one, the mob will make a rush for Fifth avenue. There are the Vanderbilt houses, those big brown buildings opposite the Cathedral. If fire were to consume them it would be a loss to the whole city, because they’ve got pictures and statues and books in them that could never be replaced. And my idea is that in time those valuable things will find their way into the Metropolitan Museum or some other public institution where they will be safe from fire and thieves, and can be seen by everybody.” “Do they often have fires in these big brown stone houses?” asked Bruce. “Not very often,” replied Mr. Trask, “but they have them sometimes in the hotels and fashionable apartment houses, and perfect death traps some of those places are. There was one fire in a dwelling-house not long ago that came near proving fatal, and would have if it hadn’t been for our hook and ladder company getting there in time. It wasn’t much of a fire either, just what you might call a little blaze and a good deal of smoke in the third story, but it came near costing a lady her life all the same.” “How was that?” inquired the boy eagerly.
