HOUSES AND CONVENIENCES. 39 



houses may be constructed, so as not to show even the 

 convenience for the heating apparatus, further than a door 

 to shut doAvn over the under-ground vault, and even this, 

 if thought objectionable, may be made to form a part of 

 one of the pathways inside. The example given is an 

 arrangement of, and now under the charge of, the writer, 

 and answers admirably. Hot water is here used for heat- 

 ing, but the same is equally applicable to the furnace and 

 common flue, with the difference of placing the chimney 

 at the opposite end. 



Since the above was written we have been apprized of 

 a method of ventilating double pitch curvilinear houses, 

 which has been invented by Mr. William Webster of 

 Rochester, and for which he is about taking out a patent. 

 His plan consists in having a movable chamber along the 

 whole length upper part of the house, and which he can 

 lift or lower at pleasure. If the machinery can be made 

 to work well and kept in permanent order, he has con- 

 ferred a great benefit upon the public, and deserves the 

 thanks and support which all such useful improvements 

 ought to receive.
