Standard Mill Construction. Where timber is in contact 

 with walls, foundation and plates, and wood touches wood 

 in first floor framing, two coats of Carbosota Creosote Oil 

 should be applied to the bearing surfaces. (Courtesy of

Little wastes multiplied 

 means big losses

'"PHE cost of treating the ends (points of contact 

 * and bearing surfaces) of girders, beams and 

 columns of "mill construction" buildings is insignifi- 

 cant in comparison with the total investment, but 



The development of decay at one point of but one 

 column or girder in the entire structure, causing its 

 weakening and necessitating replacement, may entail 

 a very considerable expense. This loss can be avoided. 



Application of Creosote Oil (Carbosota Creosote 

 Oil) to points of contact is an imperative precaution- 

 ary measure required by the specifications for "mill 



construction" approved and recently adopted by the 

 National Board of Fire Underwriters to wit : 



"Ends of girders, beams and columns, when rest- 

 ing on metal plates or masonry, shall have the bearing 

 surfaces protected by a piece of creosote-saturated felt 

 or paper, or two brush coats of hot creosote." 



Carbosota Creosote Oil is the standard wood pre- 

 servative for non-pressure processes. It is a pure 

 coal-tar creosote, highly refined and specially pro- 

 cessed to make it physically fit for the purpose, and 

 conforms to recognized standard specifications. 



(Green wood cannot be effectively creosoted by non-pres- 

 sure processes. It should be air-dry. In regions of moist, 

 warm climate, wood of some species may start to decay before 

 it can be air-dried. Exception should be made in such cases 

 and treatment modified accordingly.)
