and is closed by a tightly-fitting screw-cap, similar to that of a glass 

 fruit-jar. 



The price of this instrument is $2.50. 



For applying the Buhach and water the 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- 

 ernl 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 not 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 cineraricefolium 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 vield 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 cineraricefolium. 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. When a flower of the cineraricefolium 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 insecricidal qualities are concerned. 



The flowers of all of the cineraricefolium 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 roseum is much 

 more irregular in its flowering, continuing to produce flowers during the 

 greater part of the summer season, sometimes producing a second crop 

 of flowers the same season, but it does not blossom as profusely as the 

 cineraricefolium.
