The plant here figured is that which yields the famous 
Dalmatian insecticide powder, now so universally used, and 
the flowers of which are said to be the most valuable 
product of its native country, where it is also cultivated. 
It must not be confounded with the Caucasian insecticide 
Pyrethrum rosewm, which is cultivated in France. <A very 
valuable paper by G. B. Loring, on the cultivation in the 
United States of both these insecticides, with copious notes 
on the mode of application of their powder and preparations 
of it to insects that infest plants, is given in the Report of 
the U.S. Commission of Agriculture, cited above. From 
this document it appears that the powder of both species is 
valuable as a general insecticide, especially in a liquid 
solution, but that it is not a universal remedy, and has 
serious disadvantages. Of the advantages, the most notable 
is that it is a specific in the case of Aphides, house flies,
