less pulp. Here tlierefore it may be 

 observed, that this efi'ect may be still 

 heiglifened by giving a very faint tint in 

 one of these layers. It is true this dou- 

 ble paper would not afford all the 

 advantages derivable from the tests of 

 the interior colour, because all superfi- 

 cial colour may be laid upon ready- 

 made paper. Nevertheless, certain pe- 

 culiarities in the mode of laying in this 

 colour may be accomplislied, wliicli it 

 would be extremely difficult for the 

 forger to achieve, otiiervvise than by 

 means of pulp in the original formation 

 of the paper ; thus it may be laid on in a 

 mottled state by a peculiar formation in 

 the mould, and by the use of a tiiin 

 icopper strainer, instead of wire, in the 

 sieves, it may be laid on so as to pro- 

 duce a sort of shade to the transparent 

 water-mark; two descriptions of water- 

 mark, one dark and the other transpa- 

 rent, being thus mixed by means of the 

 two layers of paper, which would pro- 

 duce a most beautiful combined effect, 

 to be only imitated in the original con- 

 struction of the paper ; and, being per- 

 fectly indestructible, such paper would 

 also be thinner than tlie triple paper. 

 The paper thus made of different lay- 

 ers, whether double or triple, witii the 

 coloured layer or without it, is suscep- 

 tible of another indelible description of 

 mark in the interior, wiiich cannot be 

 produced but in the first formation of 

 the paper ; thus, after the first layer is 

 couched, it may be printed upon at the 

 mill, either in colour or in black. I 

 liave thus printed various forms or 

 figures, and even the promissory part 

 itself of the note, in the very heart of the 

 paper before it was finished; that is to 

 say, forming part of the first process at 

 the mill. This printing, whatever it 

 may be, may then be covered with the 

 outer layer of very fine transparent 

 pulp, either |)lain or with a transparent 

 water-mark, mixing and combining, if 

 required, with the printed character in 

 the inferior. By this exterior covering 

 it is obvious, that this printing is not 

 only protected from injury, but that it 

 cannot be set off or rubbed down for 

 the purposes of imitation. There is 

 another improved manipulation as to 

 the printing upon bank-notes, similar 

 lo the foregoing one, and productive of 

 the same effects, namely, that the 

 printing may in like mainifr be per- 

 formed u])on the i)aper in an unfinished 

 smd damjied state, and previous lo its 

 Ijcing sixcil. This manipulation on llie 

 same princi|)Io as the last-mentioneil 

 proecb-s, will protect the priiiting from 



339 



injury, and from being set off or rubbed 

 down for the purposes of forgery, though 

 not so completely as the last- mentioned 

 mode, wiiile it also improves the im- 

 pression. And this also may be best 

 performed by combining the operation 

 of printing with the original formation 

 of the paper at the mill, which neces- 

 sarily places any improved effect thus 

 attainable still further out of the rcacli 

 of the forger; in short, it is evident that 

 there is an infinite variety of these 

 tests to be obtained by the different 

 modifications of the |)rinciples herein 

 stated, which it is not necessary further 

 to describe.
