RESINOUS CEMENT. 215 



place by resinous cement or wax. The closed end of 

 the quill must project above the small end of the cork, 

 and be rendered perfectly watertight by the insertion of 

 a drop or two of wax or cement* into its interior, which 

 must be pressed into the point of the quill by a bit of 

 stick or wire. The quill must project about an inch 

 above the small end of the cork, while a piece of wood 

 the same thickness as the quill must be inserted and 

 fixed in a similar manner with cement into the under 

 and thick end of the latter, and be allowed to project 

 about an inch below it. This piece of wood is to be 

 tapered to a blunt point at its lower extremity, into 

 which is to be fixed a small ring of fine brass wire for 

 the line to run through, either by boring a small hole in 

 it with a needle, and securing the twisted extremities 

 of the wire ring with cement, or otherwise by whipping 

 it on with silk. The whole must then receive several 

 coats of varnish of a colour approximating as closely as 

 possible to the tint of the water it is likely to be used 



* RESINOUS CEMENT. The following cement will be found very 

 hard and tough, and not only useful for joining together, the different 

 parts of floats, but applicable to numberless other uses where an 

 easily applied and durable cement is required : 



Melt five parts of yellow resin and one part of bees' -wax together ; 

 then stir in one part of burnt ochre and one-eighth part of gypsum ; 

 after allowing the whole to boil for a minute or two, remove 

 it from the fire, and keep stirring it till it cools. When used, a por- 

 tion is to be melted in a gallipot or small tin capsule, and applied as 

 required. 



Burnt ochre is common yellow ochre ignited at a red-heat for a few 

 minutes in a crucible or iron lead-pan, when it becomes a deep red 

 colour.
