710 OBSERVATIONS ON THE LUNG PLAGUE OF CATTLE. 
was kept in a stable surrounded by spacious grounds, and was 
never allowed to go out. In the end of March she sickened and 
died of lung plague. 
2. Joseph Hyde, Seventieth Street and North Liver, New York, 
had lost twenty cows in four months in the spring and summer 
of 1879, and was allowed to put up a new stable for fresh cows 
two lots distant from his former one, on condition that separate 
attendants should be furnished for the two stables. The fresh 
cows were all from healthy country districts, and the stable was 
built of new wood, yet a month later the plague showed itself in 
that as well. It was then found that the attendants in the 
different stables had helped each other in the owner’s absence. 
As showing that the infection was not conveyed through the air, 
the lot between Hyde’s two stables was occupied by the house 
and cow stable of a different party, whose stock kept sound 
throughout. 
3. George Youngblood, Little Britain, Orange Co., sent a 
cow to New York by the Newburg boat, May 29th. She never 
left the pier, nor came in contact with other cattle, except those 
coming by the boats from healthy country districts, but like 
others was handled by milkmen and dealers. She was taken 
back by the Newburg boat the same day she arrived (May 30th), 
and two weeks later she sickened with lung plague, and con¬ 
veyed it to Youngblood’s herd. The cow was sent back to 
New York for sale, September 30, when she was killed as a 
diseased animal, and nearly a third of one lung was found to be 
necrosed and encysted. (Bor other cases see my report to 
General Patrick, presented to the Legislature.) 
To deny the spread of the disease by this channel as has 
been done, and to act upon this, is but to offer facilities for 
the plague to extend its ravages, and to render doubtful or 
impossible its final extinction. 
Contagion through Infected Buildings . — Beside the fact, 
notorious in all countries where lung plague prevails, that 
dealers’ stables are the grand foci of infection, and that animal's 
sold by dealers are the most prolific causes of its spread, it may 
be well to name one or two instances in which empty infected 
stables serve to propagate the pestilence. 
1. John Muller, Farmingdale, L. I., on January 1st, 1879, 
got from a dealer a cow, which soon sickened and died. Soon 
after he bought another cow, which speedily died in her turn. 
Later he got a calf from the healthy stock of a neighbour, but 
it too sickened and died, and the stable was left tenantless. 
2. Messrs. Niedlinger, Schmidt & Co., 406, East Twenty- 
seventh Street, New York, lost a cow from lung plague August, 
1878. Three months later another cow was placed in the same
