This machine was not a success. The milk from each teat 
is conveyed in a separate rubber tube to the receiver ; each 
tube has its own tap, and this great length of tubing and 
associated crevices render efficient cleansing very difficult. 
The glass sight feeds leaked and admitted air into the milk. 
If the teat cups fall off they suck up dust from the floor.

The milk passes through a similar amount of rubber tubing 
to D and E, and therefore presents the same objections with 
regard to cleansing ; likewise when the teat cups fall off they 
may suck up dirt from the floor. The construction of the can 
was such that it was difficult to clean, because of its depth, 
narrowness of the mouth and roughness of the joints.

The milk passes through a similar amount of tubing to 
D and E. There is also similar trouble with the teat cups.
