it seems that previous to 1845 it had been detected in North 
Carolina, 
The disease appeared in Michigan about 1857; the exact time 
is not known, nor by what method it was introduced. To my 
knowledge it has not been reported in Ohio or Indiana. If this 
be true it isa query how it got to Michigan unless imported in 
the fruit or young trees brought from nurseries in infected dis- 
tricts. This I believe to be the case, and have a faint recollection 
of seeing a published statement to that effect. 
The orchards of the South Haven district seem to have been 
the first to suffer, 
From the above facts of history, it will be seen that this disease 
is one that progresses slowly, and yet in one sense rapidly, and is 
as sure in its results as is pulmonary consumption. It is to be 
hoped that such active measures shall be taken that its future his- 
tory shall not cover near as much territory as at the present time. 
t is a disease that, unless checked in its progress, will follow 
wherever civilization advances.

ON THE SO-CALLED CHUKCHI AND NAMOLLO 
PEOPLE OF EASTERN SIBERIA; 
BY W. H, DALL, 
Tr natives of that portion of Asia lying east of the meridian 
of 180° from Greenwich, and between Behring sea and strait 
and the Arctic ocean, have always been regarded with particular 
interest. This interest arises partly from the fact that they alone 
of all the Siberian tribes have maintained their independence of 
Russian authority, and partly from the idea that these people 
form a link between the races of Asia and America; a thorough 
knowledge of their ethnological position being supposed to be 
all that was required to confirm or disprove certain theories of 
Migration, 
Another source of interest is the confusion that has always 
€xisted in regard to their division into different stocks, and which 
S still far from being cleared away. The forthcoming work of.
