BLOTTING PAPERS. 



The value of blotting papers is determined by their absorptive 

 power. They should be rather loosely made and the best grades 

 should not be loaded. 



WRAPPING AND BAG PAPER. 



The important qualities for wrapping and bag paper are strength 

 and pliability, which should not be sacrificed for other character- 

 istics. Jute and manila are recognized as giving a paper of this kind, 

 but any stock which will insure the properties named may be used. 

 A paper known as " Kraft brown," made by a special method of 

 treating wood, is now coming into prominence for these purposes. 

 It apparently is much stronger than the ordinary papers heretofore 

 made from chemical or mechanical wood pulps and promises to serve 

 as a substitute for jute and manila papers in certain cases. 



Papers used for wrapping polished metals should be free from acids. 

 The more perfectly wrapping papers resist water the better, provided 

 that strength is not sacrificed in securing this quality. 



DIRECTIONS FOR SECURING AND FORWARDING SAMPLES. 



If possible, each sample for examination should consist of ten 

 sheets 12 by 12 inches, and each sheet should be taken from a dif- 

 ferent part of the lot of paper. The sheets must be shipped flat 

 and so packed as not to be broken or creased in transit. 



Samples positively must not be folded or rolled. If it is impos- 

 sible to secure ten sheets of the desired size, smaller samples may 

 be taken, but the examination made may be limited by the quan- 

 tity and condition of the sample. 



Each sample must be fully identified by numbers or other marks 

 and labeled with the name of the sender; name of manufacturer, 

 when obtainable; the class to which it belongs, as "ledger," "book," 

 "writing," "blotting," etc.; the purpose for which it will be used; 

 the manufacturer's or dealer's claims as to quality, as "all rag," 

 "half sulphite and half soda," etc.; weight and size per ream, and 

 cost per pound. 



The sender should not fail to indicate the nature of the examina- 

 tion desired that is, whether compliance with specifications is to be 

 determined or suitability for a given purpose. If the former exam- 

 ination is desired, a copy of the specifications should be furnished, 

 and if the latter, the purpose for which the paper is to be used should 

 be stated.
