1 will charge 5 to 10 per cent and travelling expenses 
if employed as chief architect, but nothing for drafts 
and estimates. Of this 2 per cent must be paid in 
advance. 
If employed as builder 1 will build at the same rate 
as any other builder would for combustible (stone or 
brick) houses, receiving for remuneration the saving in 
fuel and insurance for 25 years, one fifth in advance. 
To alter any standing house or building and give it 
this incombustible property, I will charge the actual 
needful expenees to change the inside and roof with 
the saving in fuel and insurance for 10 years, 2 years 
in advance, or half of the saving for 25 years. 
I have not taken a patent for this discovery, because our 
actual patent laws give no security against vexatious law 
suits and heavy expenses, while by keeping secret a disco- 
very it may be made more profitable. This 1 have found 
by experience. The difficulty of making models would 
also be too great. But 1 will use this discovery as Mac- 
adam used bis roadmaking in England, and 1 will teach 
the art to any architect or builder for 8 1000. 
Apply personally or by letter to C. S. Rafinesque, 
Architect, &c. No. 59 North 8th Street, Philadelphia. 
Letters ought to be post paid unless enclosing remit- 
tances. I will not answer any letter asking idle ques- 
tions; unless a fee is sent; but will immediately attend 
to orders in the line of this business.

Any house owner who wishes to render his pro- 
perty fire proof, must furnish me with an account or 
plan of it, with statement of value, fire insurance, age 
and cost of fuel in it. Whereupon I will furnish the 
means (or do it myself) to render it incombustible, and 
at the same time much warmer in Winter and even 
cooler in Summer.
