compelled me to relinquish further treatment. October 3 the doctor found only 
two, size of a hazelnut. October 31 only one. [illegible] nearly all right, the 
muscles in good condition. For the last month my health Better than I can recollect 
it to have ever been. Have used an unusual amount of walking exercise 
mind very active, very happy etc. November 15th continue bright and well. On Saturday 12th 
met captain steirer principle of Dayton high school. Made very happy to learn from him that 
by availing himself of my suggestion (opening a door leading to the [illegible]) the ventilation 
of that building was greatly improved. [illegible] I think [illegible] many a man who 
has made a large sum of money. Have had a very large double [illegible] 
burning anthracite stove put up in our dining room. By opening window for a short 
time before bed hour, room below filled with pure air, and bedroom all night 
being supplied with a moderate flow of good air [illegible] 50 years ago at Greenfield 
Massachusetts I discerned and applied the principle on which [illegible] self supplying 
[illegible] work. Had band box sheet in on air tight, the doors were not [illegible] 
and where wind blew strong, admitted so much air as to burn the wood too fast. 
Had a hole cut in the smoke pipe near where it entered flue, [illegible] by a 
[illegible] piece of sheet iron. By opening this, the air rushed into the flue [illegible] 
the draft through the stove, in other words draft checked without air admitted to 
burn out wood too fast. But for the use of this principle it would be impossible to 
regulate [illegible] burners. Every door with [illegible] admits air and if this acted 
fully on the fuel without before passing into the flue a moderate combustion could not be 
maintained. Too many [illegible] doors are now made for economy of fuel.
