Caleb Mills Saville: The question has been brought to my attention by the complaints of several of our local shop keepers in narrow and congested streets. They say post hydrants are a nuisance and annoy people. Some of the other city officials have heard of flush hydrants, hydrants under the curb, and that they have been successfully used. Boston used to have some. Providence has some now, Salem, Massachusetts, had some until they had a conflagration and then they abandoned them, I think. They are very unobtrusive because they are under the sidewalk and annoy no one except the firemen on cold, stormy days. As I say they have been used in several places, and it will be interesting and instructive to know what the members here think of flush hydrants. Insurance interests have little use for them, and as far as I am informed, water department officials generally are not at all favorable to their use.
