conspicuous if in close proximity to the sea air; and I have no 
hesitation in saying that a vast extent of old wngalvanised wire 
fences, the wires of which were comparatively good, have been 
rendered useless in consequence of the injurious effects referred to. 
The only way to obviate this is to have the wires all galvanised, 
and to have the barbed wire galvanised after the barbs are 
twisted into the strands, and thus render the wire free from oxida- 
tion as far as possible. This would probably make the wire a 
little more expensive, but the extra cost would be infinitesimal 
when compared with the advantages from having a properly 
galvanised wire. 
The subject is of vital importance to all connected with estate 
management, and is worthy of more attention than it has yet 
received,

Additional Note by Mr Kay :— 
I understand that a newly patented method of galvanising has 
recently been adopted at the works of the Sharon Hill Galvanising 
Company, Darby, Pa. A most interesting paper on the process 
was read by Mr George Reese at a meeting of the Franklin 
Institute about twelve months ago. Unfortunately the paper is 
too lengthy to be here reproduced, and I simply give the following 
extracts :— 
“The process is effected by what is termed a centrifugal 
separator and the galvanising bath. The chief advantages of this 
method are that it is only necessary to subject an entire bundle 
of wire for a few seconds of time to the action of the centrifugal 
separators instead of drawing a small number of strands through 
wipers at the slow speed of not more than one foot per second, 
as in the old wiping process. The bundles are finished as fast 
as they can be raised to the proper temperature and coated in 
the galvanising bath, hence the tonnage output is enormously 
increased, 
“Among the new articles produced by this method is barbed 
wire, which is galvanised after it has been twisted into shape and 
formed into bundles. When wire is galvanised before being 
barbed and twisted, much of the coating cracks and peels off, and 
the points of the barbs, where they are not coated, become blunt 
by rusting, This new article can not only be produced much
