In examining the results on these nine papers it will be seen that 

 all except Nos. 1130, 1206, and 1207 are satisfactory as to the kind 

 of stock which they contain. In breaking length the same three 

 papers are lower than the others and show a greater loss of strength 

 under the folding test. Papers Nos. 1130 and 1207 are below the 

 standard in stretch, which for this class of papers should be at least 

 4 per cent. The three papers first mentioned also show the greatest 

 decrease in stretch in the folding test. In ash all of the samples are 

 satisfactorily low except No. 1207. The sizing of all is good, although 

 it would be better to omit the starch from Nos. 1131 to 1207, inclu- 

 sive. In reaction Nos. 1128, 1130 and 1131 are neutral, while all of 

 the others are faintly acid, which is undesirable. All of the samples 

 contain more sulphates than should be found in the best ledger 

 paper, and the same is true of chlorids for Nos. 1128 to 1132, inclu- 

 sive. Considering all the evidence, papers Nos. 1130, 1206, and 1207 

 would be rejected on stock, strength, and folding; Nos. 1130 and 

 1207 also on stretch, and No. 1207 on ash as well. The other papers 

 are all good, with the advantage in favor of No. 1128 on account of 

 its neutral reaction and small loss of strength and stretch on folding. 



CHARACTERISTICS OF PAPERS FOR VARIOUS PURPOSES. 



The selection of suitable papers for specific purposes is not always 

 an easy matter, and the following broad statements as to the char- 

 acteristics that different papers should have may be of service to 

 purchasers in preparing specifications; more detailed specifications 

 could be suggested for any particular case. 



The value of a paper may be considered from two points of view- 

 that of quality and that of utility. In the former case the question 

 of cost is considered but little, the object being to secure an article 

 of the finest kind and most pleasing appearance. Such papers are 

 used for special purposes, for example, fancy writings, editions de 

 luxe, etc., and constitute but a small part of the papers made. Con- 

 sidering the utility of a paper, it should have the special characteris- 

 tics which make it suitable for a specific purpose, the finish, texture, 

 and stock being no better than the work to be performed demands. 



RECORD PAPERS. 



The papers used for recording deeds, for court records, vouchers, 

 receipts, ledgers, and all Federal, State, and county records which 

 are preserved for many years and subject to much handling, should 

 be strong and uniform, and to this end should be of the best rags 

 and manufactured by the best processes, being well washed to remove 

 bleaching agents and soluble salts. Such a paper should not be over 

 bleached; should be well but not over sized, using animal sizing and
