tention was principally directed to the effect of the machine 
upon the milk flow. He found that this was not markedly 
affected. He also stated that a high grade of milk was secured 
but did not give the conditions under which it was secured nor 
the data upon which his judgment of its quality was based. 
STUDIES AT THIS STATION 
MACHINES USED 
The Globe cow milker (Plate III, fig. 1), which was first 
tested. was made by the Rockhill Foundry Co., at Roanoke, Va. 
The machine was exhibited at the New York State Dairymen’s 
Association meeting in Binghamton in December, 1905, and at 
the Syracuse meeting of the New York State Breeders’ Associa- 
tion in January, 1906. It was installed in the Station barn in 
March, 1906, and used somewhat irregularly until near the end 
of the year. The irregularity of operation was due to the fact 
that the vacuum pump and other accessories frequently got 
out of order. 
This machine was not a success. Aside from the mechanical 
defects above referred to there were several cows which it did 
not milk in a satisfactory manner, in some cases failing to 
remove from the udder more than one-half of the milk. As 
will be seen later the quality of the milk delivered by this 
machine when it was run according to the directions of its 
makers was extremely poor. Moreover the extra labor required 
to care for the machine more than offset the time saved in the 
milking process. 
In 1907 the Burrell-Lawrence-Kennedy cow milker (Plate ITT, 
fig. 2), manufactured by D. H. Burrell & Co., at Little Falls, 
N. Y., was installed and has been studied from that date to 
the present time. The principles of operation of this and the 
Globe machine are quite similar. In each the actual milking 
is accomplished by producing a vacuum at the end of the teat. 
A rigid teat eup with a soft collapsible upper edge for pre- 
venting the entrance of air surrounds and gently supports 
the teat and receives the milk which flows from the teat. The
