The foreign journals have lately an- 
nounced an important and fimple procefs, 
to render Leather more durable, and Icfs 
permeable to water. It is propofed to 
apply to leather what has been long 
applied fuccefsfully to the Cordage of 
- Shipping, namely, acoating of Tar, which 
is not only to be laid over its furface, 
but to be made to penetrate the whole of 
its pores. Inthe procefs, it is neceflary 
to heat the leather well on its inner 
furface, and in that ftate to apply a layer 
of hot tar, which, when dried in, is to be 
repeated feveral times according to the 
thicknefs of the leather, fo that the tar 
fhall have penetrated to the oppofite 
furface. In the laft application of the 
tar, in order to add to the durability of 
the leather, it is recommnended to powder 
it with fteel flings, which, by becoming 
as it were incorporated with it, confide- 
radly aug.nents its refiftance. To render 
Varieties, Literary and Philofophical. 224 
A 
thoes impenetrable to moifttire, it is 
farther recommended to rub the foles of 
them, from time to time, with hot tar, 
and that the inner furface of the leather 
ihould be worn on the eutfide, and not 
as is now the common prasgtice.
