very fine and this should be kept in mind in selecting 

 a grinder, since there are many grinders on the market 

 which will not grind fine enough for pig feeding. 



WATER SUPPLY 



Pigs drink a large amount of water, from twelve to 

 twenty pounds to the pig each day for mature hogs; 

 hence a good watering system is very desirable. On 

 most western farms, a waterworks system can be installed 

 with so little difficulty that not only for the convenience 

 of the pigs, but for the general improvement of the farm 

 it should be put in as soon as possible. 



WATERING DEVICES 



Since hogs require water at frequent intervals, it is 

 desirable that a system be established which will reduce 

 the labor of watering to the minimum. It seems justi- 

 fiable to go to greater expense in putting in an efficient 

 water system than ' in almost any other item of the pig 

 equipment. So far as possible, fields which are to be used 

 as pig pastures and which are not provided with springs 

 or natural streams should be supplied with pipes running 

 from a central water system. If this expense cannot be 

 entailed, a suitable device may be made of a large barrel 

 with an automatic watering equipment attached. This 

 will supply water for 1000 pounds of pigs for four days, 

 provided none is wasted. The labor of refilling the barrel 

 if the water has to be hauled adds a considerable expense. 

 A suitable device if water is piped to the pastures or pens 

 may be made with a float valve, the float being boxed 

 in at one end of the trough so that the pigs cannot break 

 it to pieces, and if the troughs are on the same level, 

 one trap can regulate several troughs. (See Plate XVI.)
