APPENDICES. 135 



Castella, is not yet finished, consequently we are not able to give a 

 drawing of it in this appendix. The machine, which is very simple in 

 construction, promises to be exceedingly valuable, if only for the fact of 

 the little labour required in working it. 



Lowe and Park's Patent Steam and Chemical Vapour Insect 

 AND Fungi Exterminator. 



{See Fig. 15.) 



This machine consists of a boiler, to which is attached an amal- 

 gamating chamber and evaporator for the purpose of amalgamating the 

 steam with sulphur vapours and other chemicals, and works as 

 follows: — When the steam is generated in the boiler, and the pressure 

 has reached 20 lbs. to the square inch, the steam is turned on at the stop- 

 cock (upon the top of the boiler), it then passes through the steam-pipe 

 to the generator and amalgamator, and there becomes amalgamated with 

 the vapours or liquids, and then passes on through the flexible hose in 

 the right form and preparation to do the work of cleaning the trees and 

 destroying the pests. 



The disinfectants and vapours are by this system forced by the pressure 

 of steam to the very bottom of every hole and crack in the tree, and 

 without any doubt reaches the bottom of the disease, thereby thoroughly 

 destroying all insect life, together with any larvae or eggs, which may 

 be at the bottom of the said holes and cracks. It also penetrates the 

 loose bark, which is the home of the dreaded codlin grub. 



These machines are made in three sizes, viz.: — 



No. 1 machine is suitable for a very large orchard, or for the use of a 

 district; it has two hoses, and intended for two men to work together 

 on the trees. Three men can move this machine about, and it will cost 

 £50. 



No. 2 machine is suitable for large orchards, and has one hose only. 

 Two men can move it about ; costs £35. 



No. 3 machine is suitable for gentlemen's gardens and small orchards. 

 One man can move it about ; costs £25.

The Greenhill Codlin-moth Lamp. 



{See Fig. 16.) 



This lamp is an invention for the destruction of the Codlin Moth and 

 other insects. The top portion consists of a vessel containing oil. From 

 this are suspended wires or threads, down which the oil trickles, falling 

 into a receptacle underneath, also containing oil. In the centre of the 

 wires or threads a light is placed, and this attracts the insects ; but in 

 making for the light they come in contact with the wires or threads, 

 Avhich disable the insects, and falling into the receptacle below they are 

 destroyed, and can be removed when necessary. The lamp is fitted so 

 that it can be suspended from the trees or on any fixture. The design
