150 Thirty-Third Annual Meeting 
Mr. Leary: That don’t stand in our climate. We have 
heavy limestone water with magnesia and iron and nothing can 
be used as a coating that will last, but for our outlets we use 
perforated zinc sheets exclusively. 
Mr. Stranahan: We believe the cheapest course is to use 
brass or copper wire entirely. We have never found anything 
that we can coat with that will not come off. 
Mr. Dean: Why use wire instead of zinc? 
Mr. Stranahan: Well, it was on hand partly when I went 
there—secondly because it gives a little bit more surface, but 
we do not need much wire. We calculate to cut our water down 
so that we won’t have much overflow at any season of the year. 
Mr. Dean: The great thing in favor of zinc is that it cleans 
easier than wire. 
Mr. Leary: It: does. 
Mr. Dean: And won’t clog up so quickly, and if you coat 
perforated zinc with turpentine asphalt it will withstand the 
action of almost any water, although there are minerals that will 
eat it. There is something in the water at our place that will 
eat it out after a while, but a zinc screen will last on an average 
of two years in our waters. 
Mr. Lydell: I have found in my experience that the best 
wire preservative is asphaltum and tar, half and half, and put it 
onto your wire when it is at the boiling point. It will preserve 
your wire for several years and will become very hard and after 
being applied and dried it is very hard to get off from the wire. 
Mr. N. R. Buller: I have found that pure coal tar with 
proper proportions of red lead and white litharge and turpentine 
put on boiling hot is the best covering. It is not easily rubbed 
off and lasts two or three years. 
Mr. Dean: The Harrington King Perforating Company of 
Chicago have a bronze metal they claim is practically everlast- 
ing in almost any weather. 
President Clark: We use ordinary galvanized wire for our
