advantage tlmt it may be used to distribute the 

 liquid from below. For tliis purpose tliu rim of 

 the distributor should be bent back so as to form 

 a more acute anj,le. Other changes necessary 

 for litis purpose have already beeii indicated in 

 tr(?iiting of previous machines. 



"There is no doubt but that these three atom- 

 izers last described are all valuable as embody- 

 ing a simple principle which may be made use of 

 at ciiiiiparatively little cost, and both to throw 

 the spray on the plants above or up among them 

 from below. That they have, in these respects, 

 a decided advantage over all the other con- 

 trivances mentioned will admit of no doubt. 



"Thk Dauchtkey Atomi/.ek. — There still re- 

 mains one machine to be described in this con- 



will be seen from the sketch, a transverse dis- 

 tributing pipe is connected with a number (four 

 in the sketch) of vertical pipes recurving at the 

 ends, which receive the nozzles, one of which is 

 represented in section in the accompanying Fig. 

 117. The noz.zle N, which is screwed to the 

 pipe, has a closed end, ;/, provided with two 

 openings, «', oppositely inclined, so that the jets 

 delivered through them meet at a point near « 

 and deflect and disperse each other so as to form 

 an extremely fine spray. The openings «' are 

 large enough to avoid being obstructed by small 

 obstacles, and the spray produced by the two in- 

 clined jets is at once copious and powerful."

nection which is highly interesting for several 

 reasons : 1st, because it is the only one actually 

 in use for the distributing of liquid from below ; 

 2d, because the construction of the pump is quite 

 peculiar ; and, 3d, because the arrangement for 

 producing the spray is not only entirely different 

 from any described in the foregoing pages, but 

 also most simple. This machine was invented by 

 Mr. William J. Daughtrey, of Salem, Ala (patent 

 No. 200,376, February ig, 1S78). The accompany- 

 ing sketch (Fig. 117) represents it as it appears. 

 It consists in the main of a pump, which is made 

 self-operating by means of a pulley, and which 

 forces air into the receiving tank and into a com- 

 pression cylinder connected therewith, thus sup- 

 plying the pressure necessary for the spray. As 



which breaks the water into particles by 

 obstruction, illustrate a valuable principle, 

 which admits of great variety and adapta- 

 tion in its application. The jjrinciple of the 

 Daughtrey nozzle is that of the old-fash- 

 ioned gas-burner, viz., two jets crossing 

 each other. That of the ordinary fish-tail 

 burner, which sends the flame through a 

 rounded slit, is still better. It has been 

 used for the first time this season, and 

 promises to supersede all others. The
