PILES TREATED IN 1895 The piles driven in 1895 were treated by Riker-Lee &Company of Galveston, now the International Creosot-ing & Construction Company, and were guaranteed forten years. They were pine piles direct from the stock,seasoned by steaming. When removed these piles werefound to be in good condition, at least 90 per cent beingfit for use elsewhere. Most of these piles were pene-trated throughout with the preservative, and in noinstance, even where the amount of oil absorption isless than the average, is there any sharp division linebetween the treated and untreated portion of thestick. The oil used in the piles treated in 1895 was whatwas then known as heavy oil, not on account of itshigh specific gravity but because at ordinary tempera-tures it contains a large percentage of solid matter. It. Air, Water and Mud Sections Creosoted Pile Treated in 1895 was imported English oil, which, as extracted from themud section, was found to have a low boiling point,containing 60 per cent of naphthalene and somethingmore than 12 per cent of tar acids. Among the pilestreated in 1895 were 110 of red cedar. These werefound on removal to have been attacked only slightlyin spite of the difficulty of injecting a large amount ofoil into this timber. EFFECTS OF BORERS ON UNTREATED AND TREATED PILES The effects of borers on the untreated pine polesdriven in 1909 for the purpose of reinforcing the oldstructure were very severe, many of the poles beingcompletely eaten through by limnoria, with evidencesalso of the toredo. These borers work from the waterline to the mud line. While the borers attack treated piles also it is notedthat in many instances where the treated piles havebeen attacked the borers have entered through of the 1895 piles that have so suffered ar
