The economy of machine-milking is due to a saving in the time and 

 labour necessary , to milk a large herd. About fh r e minutes per cow 

 is saved where four cows are . milked at once and more time when one 

 man operates three machines milking six cows at one time. The cost 

 of operating two machines by electric motor was about 2d. per hour. 



The bacteriological examinations showed that the germ content was 

 slightly decreased and the keeping quality of the milk was somewhat 

 improved by machine-milking. Veterinary examinations showed no 

 appreciable effect on the udders or the general health of the cows, as a 

 result of machine milking. 



The experiences of 41 dairy farmers, covering periods of one month 

 to over two years, indicated that a majority of them were favourable 

 to the machine. Some 27 reported favourably, eight were undecided, 

 and six were unfavourable. 



The conclusions reached by the writers of this Bulletin are that the 

 success of machine-milking depends largely upon the man operating the 

 machine. In herds of 30 cows or more machine-milking is both practical 

 and economical, and the machine itself seems durable and efficient, 

 provided it is properly cared for by an efficient operator. 



The necessity for efficient working is strongly emphasised, and it 

 is stated that the adoption of machine-milking with the present develop- 

 ment of the machine, can only be recommended under conditions where 

 the farmer is able to give personal attention to the operation of the 

 machine, or has reliable intelligent help who can and will follow the 

 directions of the manufacturer as to care of the machine, manipulation 

 of the udder, stripping the cows, &c. 



Where such is the case the milking machine can be recommended 

 for the general dairy farmer who has a large herd, or for farmers 

 owning smaller herds, e.g., 30 head or perhaps less, who will be able 

 to attend to the milking of the herd, alone or with the help of a boy, 

 by means of the machine, and thus avoid keeping extra help for this 

 purpose. The milking machine is not definitely recommended for pure- 

 bred herds where the maintenance or the development of a maximum 

 dairy production in the cows is of vital importance, although it is 

 believed that under favourable conditions it may also prove of value in 

 such herds. 



OFFICIAL CIRCULARS AND NOTICES. 



The Board of Agriculture and Fisheries have addressed the following 

 circular letter to local authorities in Great Britain :— 



Sir, — I am directed by the Board of 

 Ordnance Survey Maps. Agriculture and Fisheries to inform you that 



a general revision of the Ordnance Survey 

 maps on the scale of one inch to a mile and on smaller scales, takes place 

 at intervals of 15 years, and that, except in the case of railways, changes 

 which take place after such a revision have not hitherto been shown on 

 the maps until after the next general revision of the district. The 

 Board propose, however, in the future to include in the maps any 

 important additions, alterations or corrections in the case of other detail, 

 such as the construction or demolition of main roads, canals, bridges,
