118 TWENTY-FIFTH ANNIVERSARY REPORT. 
Machines which gave promise of accomplishing the desired end 
began to be put upon the market in 1905, and one called the Globe 
was purchased in December of that year. It was installed the fol- 
lowing May and used until it finally broke down in September of the 
same year. During this time it was used upon eighteen cows with 
varying success. While it sometimes milked certain cows in an 
acceptable manner, it often failed to do so, and in some cases was 
a complete failure from a mechanical point of view.’® The quality 
of the milk obtained through its use was also poor. A bacteriologi- 
cal examination of the milk as it came from the machine on thirty- 
nine trials showed an average of 801,000 germs per cubic centi- 
meter, while thirty-six trials of hand-drawn milk under the same 
barn conditions gave an average of 16,800 germs per cubic centi- 
meter. 
While the results with this machine were not such as to entitle 
it to be considered as a successful milker, they were distinctly prom- 
ising in that they were so near a success that they gave strong 
hopes for the future. 
In March, 1907, a Burrell-Lawrence-Kennedy cow milker was in- 
stalled and is at present in use upon twenty-two cows. The machine 
obtains apparently all of the milk that the cows are prepared to 
give, since after-milking by hand does not produce more milk than 
would be normally obtained by the same process applied after the 
usual hand milking.2° The influence of the continued use of the 
machine upon the productivity of the cows can only be computed 
after a considerable interval. 
The germ content of the milk obtained with this machine is 
markedly lower than with the machine formerly tested. A large 
part of this reduction is due to the practice of keeping the milking 
tubes in a brine solution during the intervals between milkings. A 
further reduction was brought about by the use of cotton filters 
to remove the foreign particles from the barn air which entered 
the machine while in use. When all the details are carefully at- 
tended to it is possible to obtain milk with a germ content consider- . 
ably lower than would be obtained by hand milking under similar 
barn conditions.
