ponds, coated with asphaltum. It is put on when necessary to 
renew. It will last from one and one-half to three years, and 
this wire as you know costs from five to seven cents a square foot. 
I think if it was used it would be found the cheapest and best. 
Zine costs a great deal more and the galvanized wire answers the 
purpose. 
Mr. N. R. Buller: I use the galvanized wire altogether, but 
I think with the addition of red lead and white litharge to the 
plain asphaltum it becomes harder than it does in its natural 
state and will last a year or two longer than if we use the pure 
asphaltum as a coating.
