is carried by an elevator to a separator which, by proper sieves, sepa- 
rates the coarser particles of the grist, allowing only the finest, dust- 
like powder to pass through. This powder is carried by an elevator to 
an adjoining building, where it is put up in tin cans for the market, 
while the coarser particles thrown off by the separator are returned to 
the millstones again. 
The flowers become considerably heated while being reduced to a 
powder, but the latter, in passing through a large series of elevators, 
loses its heat to a great degree before it is put into the cans for the 
market. 
This powder is put up in tin cans of five different sizes, holding re- 
spectively 2 ounces, 5 ounces, 10 ounces, 1 pound and 6 pounds. The 
2 ounce and 5-ounce cans are packed into boxes containing a dozen 
cans, and also into cans of 12 dozen cans each; the 10-ounce and 1- 
pound cans are packed into boxes containing a dozen cans each, and 
the 6 pound can into boxes holding 6 cans. 
Each can of powder bears the company’s trade-mark, which is a guar- 
antee of the purity of the powder contained therein. The design of 
this trade-mark consists of an enlarged figure of a flea above, and a 
figure of a grasshopper below, while between them are the words: 
‘Buhach: G. N. Miico’s California Universal Insect Exterminator,” and 
in the upper corners are the words ‘‘Trade-mark.” The essential ele- 
ment of this trade-mark is the word Buhach. 
Mr. Milco informs me that two years ago a certain firm doing busi- 
ness in this State undertook to put a fictitious article upon the market 
under the name of Buhach; the Buhach Producing and Manufacturing 
Company brought a suit against them, but as the said suit has not been 
decided up to the present writing it is impossible to say what the out- 
come will be. 
Mr. Milco made the first experiment to introduce the growth of the 
Pyrethrum cineraricfolium into this State in the year 1870. In 1873 he 
sold a few pounds of the powder, at the rate of $16 per pound. In 1878 
he raised about 900 pounds of the powder, which at first he sold at the 
rate of $4.50 per pound, but finally reduced the price to $1.25 per pound. 
In the year 1879 Mr. J. D. Peters united with Mr. Milco in the eulti- 
vation of the Pyrethrum cinerariefolium and the manufacture of Buhach, 
under the firm name of the ‘*Buhach Producing and Manufacturing 
Company,” and for several years they sold the Buhach at the rate of 
75 cents per pound, wholesale. 
The present price of the Buhach is as follows: 
The 6-pound cans are sold to the largest wholesale dealers at from 
45 to 50 cents per pound; the wholesale dealers seil them to retail deal- 
ers at the rate of 564 cents per pound, when a case of six cans is pur- 
chased at one time, but when less than a case is taken the price is 60 
cents per pound. The retail dealers sell these cans to consumers at the 
rate of 75 cents per pound when the whole can is purchased at one time,
