* Still less — to be known of the discovery and history of 
the Dalmatian species of Pyrethrum (Pyrethrum cineraric- 
Jolium), but it is probable that its history is ee similar to that 
of - Asiatic species. At the present time the Pyrethrum 
flowers are consider ed by far the most xeipsbis product of the 
it of Dalmatia.” (Pp. 164-165.) 
CULTIVATION. 
“There is also very little information published regarding 
either the mode of growth or the cultivation of Pyrethrum plants 
in their native home. dd to the Caucasian species, we have 
reason to believe that they are not cultivated, at least not at the 
resent time, statements to the contrary notwithstanding. Dr. 
Gustav Radde, Director of the Imperial Museum of N atural 
History at Tiflis, Transcaucasia, who is the highest living authority 
on everything pertaining to the natural history of that region, 
wrote us recently as follows :— The only species of its genus, 
Pyrethrum roseum, game gives a good affective insect powder, 
is nowhere vola but grows wild in the basal-alpine zone 
f our mountains at an altitude of from 6,000 t o 8,000 feet. 7 
seed of phia s species. He writes that his agents were not able to 
get more than about half a pound of the seed from any one 
person. From this statement it may be inferred that the seeds 
— be gathered from the wild, and not from the cultivated 
pia. 
“As to the ——— plani, it is also said to be cultivated in 
its native home, but n get no definite information, owing 
to the fact that! the inisibitarita are very unwilling to give any 
information regarding a plant, the product of which they wish 
to monopolize. Forsimilar reasons we have found great difficulty 
in obtaining even small E Pp ER of the seed of P, cinerariæfolium 
that was not baked, or in other ways tampered with, to prevent 
germination. Indeed, the people are so jealous of thar plant that 
to send the seed out of the co ountry becomes a serious matter, in 
which life is risked.” (P. 165.) 
CULTIVATION OF C. ROSEUM IN FRANCE. 
“Tn 1856, Mr. C. Willemot made a serious attempt to introduce 
and cultivate the plant on a largescalein France. As his accoun nt 
of the cultivation of Pyrethrum is the best we know of, we quote 
here his experience, with but few slight omissions : * The soil best 
extremely sensitive to an excess of Hbc. and would in such 
cases immediately perish. A southern exposure is the most 
favourable. The best time for eig the seeds in athe ground 
rom March to April. It can be done even in the month of 
usd if the weather will permit it. After the soil has been 
prepared and the seeds are sown, they are covered by a layer of
