triiliiig cost. The principal drawback to it as at present constructed 

 by jMr. Biukley is that it is made in one piece, so that in case a larger 

 object obstructs the orifice there is some difficulty in removing the 

 same. 



"This defect could be easily remedied by making the cone in two 

 pieces, the nozzle itself to be screwed on to the basal or soldered i)iece- 

 The plates and the orifices should be thoroughly cleansed and dried 

 after use, in order to prevent rusting. The machine with four spouts, as 

 in the figure, throws the spray over six or seven rows, but its capacity 

 is easily increased by lengthening the transverse pipe (c). Its cost is 

 less than $10. 



'Lifter witnessing this machine in operation, I am satisfied that the 

 atomizing principle is a most valuable one, and that with moditied con- 

 ducting pipes or tubing, so as to throw the spray from near the groun-d 

 up into the plants and on the under surface of the leaves, as in Mr. 

 Daughtrey's machine, it will give great satisfaction because of its cheap- 

 ness and simplicity. 



•' The Goodin Sprinlder. — This machine, invented by Mr. James L. 

 Goodin, of i\rontgomery, Tex. (patent Xo. 198014, December 11, 1877), 

 is represented by the accompanying cuts. [Fig. 4 of Plate LIY] is a top 

 view, and Fig. 3 a side view of the same. The letter A represents a tank 

 or any other vessel to receive the poisoned liquid. 



" lu tlie lower part of the forward end of the tank, A, is secured a discharge-pipe, B, 

 the inn-r end of which is provided with a valve or ordinary sirup-faucet. The stem, 

 C, of the valve or faucet passes up through a hole in the foj) of the tank, A, and its 

 upper end is pivoted to the end of a lever, D, which is pivoted to a short standard, 

 E, attached to the top of the tank, A. 



'•To the forward end of the pipe, B, is attached a cross-pipe, F, from the forward side 

 of tha center and ends of which project short pipes, G, having heads, H, attached to 

 their forward ends. The heads, H, are perforated with numerous small holes. The 

 pipes, B F, are jointed as shown in the drawing, so that they may be lengthened or 

 shortened as circumstances may require." 



^¥olfram''s Machine. — One of the more recent machines is that repre- 

 sented in Plate LI. It is patented, No. 241577, May 17, 1881, by Mr. 

 John A. Wolfram, of Meyersville, De Witt County, Texas. This de- 

 vice is specially interesting as another attempt to poison the under- 

 surfaces of plants, and this is expressed by Mr. Wolfrain as follows : 

 "- The object thereof is to construct such machines or devices in a man- 

 ner as will render them easy of operation, and sprinkle the plants from 

 above, below, or underneath the leaves at one and the same time, 

 thereby touching every portion of the plant and so destroying every 

 insect that may be on it without any unnecessary waste of the poison- 

 ous liquid." The constructions and operations of these devices he de- 

 scribes as follows : 



"In the accompanying drawings A represents a suitable reservoir or tank for hold- 

 ing the poisonous liquid, said tank being secured in any suitable manner to a carriage 

 or truck, B.
