D.— GENERATOR BLOWERS. 
[Plat*- XXXVII.] 
The feeding, atomizing, and distributing devices already described in 
•ther kinds of blowers may be operated by steam blasts, and lor this 
purpose can be combined with any ordinary generator that will supply 
volume enough of steam and serve therewith as a force-medium. Many 
special examples of sock combinations might be described, but only 
one will be uotieed as appearing in the description below. 
u The st< iiunann Vaporizer. — This was invented by Mr. Charles Stein- 
mann, of Napoleonville. La. (patent No. 74185, February 4, L868). Its 
character may be thus briefly given : steam is raised bya transportable 
^team-boiler, and issues from a series of jet oipes or nipples. At the 
same time some cheap oil, as kerosene, lard, or cotton-seed oil, is made 
to drip from a reservoir over the orifices from which the steam escapes. 
The oil is thus vaporized and envelops the rows of plants between which 
the machine is to be drawn. The inventor claims that the vapor kills 
the worms without injuring the plant, and that one application will pro- 
tect the field for the rest of the season, and that his invention - upon 
its general use will finally exterminate every tribe of insect,' &C It is 
hardly necessary to say that the two latter claims are Utopian and ex- 
travagant. 
"The following is a description of this machine in the inventor's own 
words; the Plate XXXVII, Fig. 1, being a side elevation, and Fig. 2, 
a rear end view of the machine: 
"A represents the receiver or reservoir to contain the oil, and B a funnel for supply- 
ing the boiler with water, and which connects directly with a heater, E, that is placed 
•n top of the boiler, Instead of with the hoiler proper, in which heater a supply of 
water is always kept, to he heated hy the radiation of heat from that part of the 
boiler or shell of the boiler on which it rests. The interior of the heater is connected 
with the Ulterior of the hoiler, F, by two pipes. H and O, which are each provided 
with a stop cock. By this mode of connection, the wator in the heater can he re- 
tained or driven into the hoiler at pleasure, it being.ouly necessary to keep the cocks 
closed to retain it, or to open them to force the water into the hoiler. The latter re- 
unit is accomplished by the pressure of the steam through pipe, H, the water going 
into the boiler through pipe, O. Whenever the water is thrown out of the heater into 
the boiler, the former should be refilled through the funuel, B, the stop-cock, in the 
short pipe, R, to which it is attached, being opened to allow the water to euter. On
