Tal 
and is closed by a tightly-fitting screw-cap, similar to that of a glass 
fruit-jar. 
The price of this instrument is $2. 
For applying the Buhach and coe fine company has a small pump, 
which is attached to a galvanized iron vessel holding about 8 gallons. 
To this pump is attached 10 feet of rubber hose, to the end of which is 
affixed a small iron tube 5 feet in length, and so constructed that sev- 
eral of them can be fastened together, end to end. To the tip of this 
is attached a cyclone nozzle, which is screwed on to the end of the iron 
tube. This nozzle was introduced by the Department of Agriculture a 
few years ago, and is far superior to any other nozzle that I have ever 
seen. 
The pump consists of a strong brass tube about 2 feet in length, into 
. which is fitted a piston or plunger, which is operated by one hand, while 
with the other the tube containing the nozzle is moved about at the will 
of the operator. 
The present price of this pump, complete, is $15. 
The cost of setting out an acre of Pyrethrum plants varies considerably, 
but should not exceed $90. If the plants are set out in rows 4 feet apart, 
and 2 feet apart in the rows, it will require about 5,445 plants to the 
acre. The plants should et cost more than 1 cent apiece, if grown by 
the person intending to plant them out, and the Buhach Company offers 
to send a package of the seeds of Pyrethrum cinerariefolium sufficient 
to plant an acre for the sum of $5. 
There will be little or no income from the plants the first year that 
they are transplanted to the fields. After the second year the plants 
will yield from 300 to 600 pounds of dried flowers to the acre, but when 
the winter is dry and cold the plants will not yield more than 150 to 200 
pounds of dried flowers per acre the following season. 
The kind of Pyrethrum now grown upon the Buhach Company’s plan- 
tation is the cinerariefolium. There are a few plants of the P. roseum 
growing in their nursery, but this species is not considered by them to 
be so desirable as the former species, although it is hardier and easier 
to start from the seeds. Whena flower of the cinerarivfolium is crushed 
it gives forth a very strong odor peculiar to itself, and doubtless exist- 
ing in the insect-destroying property of these flowers. The flowers of 
P. roseum give forth no odor when crushed, and the powder made from 
them is far inferior to that made from the flowers of cineraricefolium, as 
far as its insecticidal qualities are concerned. 
The flowers of all of the cinerariefolium plants appear at the same 
season of the year, or within a short time of each other, thus permitting 
the whole field to be harvested at one time, whereas the rosewm is much 
more irregular in its Howering, continuing to produce flowers during the 
greater part of the summer season, sometimes producing a second crop 
of tlowers the same season, but it does not blossom as profusely as the 
cinerariefelium.
