may be facilitated by carefully wiping the inner ferrules with a 
silk pocket handkerchief before putting the rod together. 
Fig. 4 shows the joint when united. 
The only drawback that I see to this fastening is that, 
should either the fine outer, or ‘doubled,’ ferrule get dinted, or 
damaged in any way, the joint will, of course, absolutely fail to 
close. In order to make such a contingency impossible there 
ought to be plugs for both halves of the joint. 
A still simpler jointure than the ‘Simplex,’ and one, I should 
say, in every way most admirable and efficient, is Bernard’s 
Lock joint (see figs. 5 and 6), in which the upper ferrule, 
furnished with a projecting ‘rim,’ is simply slipped down into 
its place and turned under a ‘catch’ (attached to the lower 
ferrule) till the rod rings are in line, by which process the 
joints are effectually locked. This jointure is also ‘ water- 
proof.’ 
Farlow, who exhibited at the Fisheries Exhibition a joint 
on a completely different principle—a screw ‘nut’ locking the 
inner and outer ferrules-—has since registered another lock-fast 
jointing, on a new and, as it would appear, much improved 
plan, viz. that of a movable band, &c. (figs. 7 and 8.) 
Lastly we have Messrs. Hardy Brothers’ ‘patent lock-fast ’ 
joint, which is thoroughly sound and serviceable, and also 
waterproof. The method of fastening the attachment is shown 
in fig. 9 of the engraving, where the two portions of the joint 
are seen separate, whilst fig. 10 shows the joint when locked 
and in position. 
The spiral wire on the outside ferrule gives some additional 
strength where most required, and Messrs. Hardy’s system of 
brazing an additional short ferrule, the same size as the outside 
ferrule, on the top of the inside one, is a decided advantage, as 
it strengthens the joint just at the point where so many break-
