    "Mr. Charles W. Mervin, Architect and Builder, calls to my attention the fact that as brick chimneys 
    are now fashionable in Crockett, the following instructions may be useful to our brick masons.  The 
    Scientific American states that if two feet above the throat of your chimney you enlarge the opening to 
    double the size, for a space of two feet, then carry up the rest as at first, your chimney will never smoke."
