FEEDING THE FLOCK 
373. The flock in summer.— Unlike stock cattle, the flock of 
sheep must receive careful attention in summer as well as in winter, 
particularly in those regions infested with stomach worms, — the 
sheep’s greatest enemy. These worms have done more to dis- 
courage the propagation of sheep than all other causes combined, 
especially on the fertile farm lands in the central states. These 
pests seldom trouble sheep in cool regions, or in cold weather. 
Lambs are especially susceptible to attack, the older suffering 
much less and being more easily managed in summer. 
374. Pasture for sheep. — Pastures for sheep need similar care 
to that suggested for cattle pastures. The stand of grass, the 
drainage of the soil, and keeping down of weeds deserve much 
attention. It is even more important that they be kept free from 
weeds, particularly burrs of various kinds, as these are especially 
injurious to the wool, p. 182. 
Sheep thrive on pasture as nowhere else. _ They are particu- 
larly adapted to grazing short forage, and prefer it, as it is tender 
and juicy. In fact, sheep often keep parts of the pasture grazed 
so closely as to injure the plants, while the grass in other parts 
of the same field is left to grow up and seed. This can be pre-
