8. Cause and Bearing of Variations in Yield and Composition 



OF Milk. 



Summarizing the results which we have been studying we 

 have observed that — 



(1) There was an increase of milk and cheese from May to 

 June and then a variable decrease during the following months, 

 except that in September there was an increase over August.
