Cooling of the Evening's Milk. 

 By coolinif milk we reduce the tera[)erature, and by reducing the tempera- 

 tun^ the ai-tivity of the germs that cause souring is checked. The most 

 favourable tem[)erature to hold milk for cheesp-making purposes is 6-)" Fahr. 

 A certain development of lactic acid is essential to keep the undesir-able 

 organisms in check, and it will be found that the best results will be obtained 

 ai- t 'at teni|)erature. It is to be regretted that th^re are not much better 

 methods adopted in the cooling of the night's milk than those which at present 

 exist in the average South Coast dairy, In fact, in some places no attempt is 

 made to cool the milk ; it is .simply allowed to stand until the morning, when 

 it i- generally in an over-ripe condition — it is impossible for any cheese-maker 

 to make good cheese out of over-ripe milk — and the majoritv of complaints 

 which arise are due to the fact that proper care and attention h:i\ e not been 

 given to the night's milk. Every up-to-date daii-y farmer should have 

 facilities for cooling the night's milk. The little expense inciu red in erecting 

 a small building to cool and keej) the milk in would be rctuincd in the 

 increased pric(^ obtaimjd for the product. A concrete tank in the ground to 

 catch the rain-water from the roof of th(» milking shed, an elevated 400 gallon 

 iron tank, a small hand pump, and a small spiral cooler are the necessai-y appli- 

 ances. Tlie water, after circulating through the cooler and performing the 

 operation of cooling the milk, can be allowed to inn back into the under- 

 ground tank. A sketch of a small dairy and cooling apparatus, which are 

 within the means oi every dairy farmer, are shown in tigs. 2 and 3.
