hand at a moderate cost. What is urgently needed is an inex^ 

 pensive machine to peel sap willows. The machines now in use 

 are designed for peehng steamed willows which are not so valu- 

 able on the market. Moreover, the high cost of the machine 

 operates against the small growers and dealers and limits the 

 industry. Many suggestions are offered for improving the situa- 

 tion.

Fire Retardent Paints for Shingles. By Henry H. Gardner. 

 Bull. No. 42, Educational Bureau, Paint Manufacturers' Assn. 

 of the U. S., Phila., 1914. Pp. 26. 111. 



The writer of this paper is the assistant director of the Institute 

 of Industrial Research, Washington, D. C. There has recently 

 been much publicity given to the campaign against the wooden 

 shingle and this article is in refutation of many of the charges. 

 It is Mr. Gardner's belief that the wooden shingle will always 

 be used to a considerable extent. "Its moderate cost, light weight, 

 low heat conductivity, wide application and durability, are prop- 

 erties which recommend its use upon dwellings, bams, and other 

 structures of this type." 



The disadvantages of the wooden shingle are considered in 

 detail, but "very few materials have ever been made which 

 have proved satisfactory for roofing or other building purposes 

 without some surface treatment." The main trouble with wood 

 is that it is used in the natural state. The object of the paper is 

 to point out the advantages to be gained by applying various 

 kinds of fire-retarding paints. He concludes that "shingled struc- 

 tures of all types, when properly painted, are not only fire resist- 

 ant, but they are moisture proof and highly ornamental." 



Various methods of testing fire- retarding paints are discussed 

 and standards recommended.
