The tendency of the following paragraph is to show that 

 Johann Faber, at least, does not use Siberian plumbago, and the 

 fair inference from what is stated would seem to be that " Graphite 

 Broye" pencils are made wholly of finely-ground black lead, 

 although I suspect no pencils are now manufactured without 

 some mixture of clay : — 



"Johann Faber 's Finest and best Lead Pencils, Graphite 

 Br oyer — These lead pencils are made from the very finest graphite 

 procurable. The graphite, after undergoing a series of washing 

 and grinding by the most delicate and improved system in exis- 

 tence, thus rendering it perfectly pure, is very highly compressed. 



My Graphite Broye pencils stand unexcelled as the finest 

 drawing material in existence, combining all the qualities which 

 art can demand : 



1st. Their points are firm and keep well, 



2nd. The lead consists of one piece throughout. 



3rd. They are absolutely pure and free from any particle of 



grit or foreign substance. 

 4th. The degree is maintained throughout, whether hard or 

 soft. 



5th. The most renowned artists throughout Europe all testify 

 to the superiority of these " Graphite Broye" pencils 

 over the so-called t; Siberian" or " Spanish Graphites."
