over the cows' shoulders. From this pipe a 

 short branch descends between every alternate 

 cow, having on it a vacuum cock. To work 

 the apparatus one end of a rubber tube is 

 put on to this branch, while the other end is 

 connected to the pulsator, which rests upon 

 a cone-shaped pail placed between the cows 

 near the manger. 



From the pulsator two rubber tubes branch 

 out, right and left, one to each cow, and each 

 tube is attached to four rubber teat-cups, 

 which are slipped upon the teats of the cow. 



When the vacuum cock is turned on, the 

 pulsator commences to work, and causes the 

 cups to collapse and expand, and thus suck 

 the milk from all four teats at once, an 

 almost exact imitation of the calf sucking its 

 mother. One machine with a man and boy 

 is said to do the work of six men skilled in 

 milking, and with less labour to themselves. 

 This machine is also working on two or 

 three other farms, and is said to be giving 

 satisfaction.
