Replacement of porch columns and joists in 

 framing of three floors is an annual uccur- 

 rence at most apartment houses of this type. 



Arrows point to a badly rotted column on the 

 third floor, to a new column just put in on 

 the second floor, and on the walk to rotted 

 columns and stringers already taken down. 



The Dangers of Decay 



Wooden back porches and stairs of ai)artnient buildinj^s, 

 factories, warehouses, and other industrial structures must 

 be protected against decay to avoid becoming a serious 

 menace to tenants, employees, and the public; likewise 

 to reduce the continual expense of replacement, piece by 

 l)iece. 



The grade of lumber generally employed and the nature of 

 the exposure, cause rapid development of decay and unsus- 

 pected weakening of the structure, particularly at points 

 of contact. 



It is, perhaps, a very small detail — to protect these struc- 

 tures from premature decay, but a precaution that the 

 builder should encourage from the standpoint of safety 

 and economy. Elimination of decay is physical protectinn 

 to all, children and adults alike. 



Carbosota Creosote Oil, properly applied to points of con- 

 tact before erection, will retard decay and materially increase 

 the life of even the cheapest lumber. 



Used as a stain, it gives the structure a practical and 

 attractive dark brown color at considerably lower cost 

 than paint. 



Carbosota Creosote Oil is a pure refined coal-tar creosote, 

 standardized for non-pressure treatments. 



Wood Preservation is a "Safety-First" measure. 



( Green wood caiuwt he effectively creosoted by non-pres- 

 siire 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. E.rceptions should be 

 made in such cases a)id treatment modified accordingly.)
