will give a clear view of the production of butter from Dutch cows, 

 butter was weighed on delivery. 



The 



The following list may serve as a comparison: At Mrs. Beckhusen's at 

 Rastede, Oldenburg (Oldenburg is in the northwest part of the German 

 Empire). In 1874, 447.5 kilograms of butter were made from 12,609 litres of 

 milk; so they required 28.2 litres of milk to produce one kilogram of butter. 

 From November 1, 1874, till October 30, 1875, 34.4 litres of milk were required at 

 the same farm to produce one kilogram of butter. 



Gustaf Schwartz, at the farm of Hofgaarden (Sweden), the inventor of the 

 ice method, required, in 1874, 30.75 litres of milk for one kilogram of butter. 



Staatsrath Tesdorf used in the ten summer weeks from June 20 till 

 August 14, in 1873, 33,743 kilograms of milk, or 32.46 litres ; in 1875, 28,719 

 kilograms of milk, or 27.99 litres, and produced in 1873, 22,904 kilograms of 

 butter from 661,972 litres of milk (28.9 litres for one kilogram of butter) ; in 1874, 

 21,751 kilograms of butter from 637,217 litres of milk (29.3 .litres for one 

 kilogram of butter); in 1875, 20,701 kilograms of butter from 581,241 litres of 

 milk (28.1 litres of milk for one kilogram of butter). 



The latter states that the difference in weight between new butter and 

 that which was delivered, amounted in 1873, to 4.7 per cent; in 1874, to 6.6 per 

 cent, and 1875, to 7.4 per cent. From this we see that to deliver one kilogram 

 of butter in 1873, 30.32 litres of milk were required ; in 1874, 31.37 litres, and in 

 1875, 30.34 litres. 



At Rosvang, Denmark, in 1873-4, 30 litres and more were required for one 

 kilogram of butter, weighed as soon as it was churned, and 33.6 litres on 

 delivery. 



At Count Schlieffen's, at Baden in Mecklenburg (a fertile province between 

 the Elbe and the Baltic, noted as being the place of origin of the celebrated 

 Rosenstein breed) in September and October, 29.1 litres of milk (from 122 cows) 

 were required to produce one kilogram of butter.

At the farm Lampspringe, near Hildesheim (in the southern part of Han- 

 over), 37 kilograms, or 35.9 litres, were required from sixty cows, from May 1 

 1877, to March 1, 1878. 



Hofmeester, in Ingolstadt (on the river Danube in Bavaria). The milk 

 was probably from one of the South German or one of the Swiss breeds. In 

 1871 was stated to require for one kilogram of butter 28.48 litres of milk from 

 123 cows, and churned after the Holstein skimming system. 



Hoist, near Svenstrup (Schonen), requires, on the average, 27.86 litres of 

 milk from sixty-three cows. 



At Aas (Norway), 32.75 litres are required. 



Loepen, at Menzlin, produced from October to February, from 49,616 litres 

 of milk. 1,916 kilograms of newly churned butter, or 1,782 kilograms on deliv- 

 ery; so 25.5 litres, or on delivery 27.8 litres of milk were required. 



At the farm Lillyrup, Jutland (Jutland cows are often very small, valuable
