Such isolated houses are healthy, and the animals get plenty of 

 exercise and grazing. On the other hand, the labour entailed in 

 attendance, cleaning, and feeding is greater than in the centralised 



system, and the fencing of the camps is somewhat expensive. The 

 amount of labour may be reduced by employing a horse and trolley 

 to cart the slops about.
