Fig. 8. — Two " Vermorel " nozzles (American make), with disgorgers, on brass Y 

 The caps have very minute holes, and are slightly funnelled on the inside rounc 

 the hole. 



Fig. 9. — Improved "Vermorel" nozzle (English make) with disgorger. The caps 

 have small holes (bevelled at the edge from the outside) of thi-ee sizes. Th( 

 nozzle can be adjusted, by means of the winged screw, to spray in any direction) 



Fig. 10. — " Mistry" nozzle, with disgorger. A removable circular disc (shown tc 

 right, below), made of hardened tool steel, with a minute opening (bevelled al 

 the edge from the outside) fits into the cap of the nozzle, as shown. The nozzh 

 can be adjusted, by means of a screw, to spray in any direction. Made of bronze,

Fig. 12. — " Mistry Junior" nozzle. The fluid is sent up through the opening showr 

 below, to right ; it then meets the thick brass disc (shown in the lower row, middle. 1 

 and also, in position, in upper row, to right) through which it is broken up witr 

 a rotary motion into two jets which escape through two slanting channels in th€ 

 brass disc ; on the top of the thick brass disc is placed (separated by a leather 

 washer) a thin disc of hardened tool steel with a small opening, bevelled at the 

 edge from the outside (upper row, second on right), by which means the jets are 

 broken up into a smoke-like spray (see Fig. 6). The two discs are fixed in 

 position by the screw-cap, shown by itself in upper row, second on left ; 

 enclosing the discs, in upper row, on left ; and screwed in position in the nozzle 

 below. Made of brass. 



Fig. 13. — "Spramotor" nozzle, a "three-cluster." The cap of each nozzle has a I 

 deeply bevelled opening, into which, from the inside, a small perforated disc fits. 

 The nozzle, if blocked, can be cleared at once by a simple and very effective) 

 contrivance : each nozzle can be pulled down (as shown in the lower " cluster," 

 on left) until the disgorger-pin projects through the opening of the disc and so 

 clears it. When in action the force of the spray keeps the nczzle pushed out, as 

 in the upper " cluster." 



THE ORGANISATION OF THE MILK SUPPLY. 

 J. Nugent Harris. 



Secretary of the Agricultural Organisation Society. 



One of the most important agricultural problems of the 

 present day is the efficient development of a pure milk 

 supply, and although various methods have been suggested 

 from time to time, they have generally involved the applica- 

 tion of compulsory measures which would be most distasteful 

 to many of those principally concerned. The object aimed at 

 can, however, be effectively and economically carried out by 

 a system of organisation in which the producers themselves 

 voluntarily undertake to comply with the conditions necessary 

 to ensure, not only the production, but the supply to the 

 consumer, of milk which is above suspicion. These condi- 

 tions are, it is true, far-reaching, including as they do healthy
