Milk. 
3. Season of the Year and Food. — In the spring of the year and 
the early part of summer, milk is more abundant and of a finer 
flavour. As the season advances, the supply diminishes, but be- 
comes richer in butter. Thus two samples from the same dairy 
and cows out in grass, analysed by me in August and in Novem- 
ber, yielded the following results : —

The same quantity of milk, it will be seen, which in August 
scarcely yielded 3 per cent, of pure butter and 3 per cent, of curd, 
in November produced 1^ per cent, more butter, and ^ per cent, 
more curd. Cheese-makers are well acquainted with the fact, 
that in autumn the quantity of milk diminishes considerably, 
but that the weight of cheese which can be made from a given 
quantity of milk is much greater than in spring or summer.
