PRACTICUMS 
1, CHoostnc Somine Crors.—Require each student to prepare a 
table of soiling crops that will afford a succession of green food 
from early spring until late fall. In the table should be included 
the name of the crop, the time of seeding, amount of seed to the 
acre for that crop and the time of cutting for use as feed. 
2. Locatinc DisEasE.—Every student of farm animals should be 
familiar with the common diseases and whether they are general or 
local in nature. He should know what regions or parts are affected 
by particular diseases. By means of the illustration on page 455 
point out the diseases that affect each part of the horse. All ani- 
mals being judged should be looked over for blemishes or other 
disease troubles. The student should be able to tell where every 
common disease is located. Often several of these ailments may 
be found in the same horse. Require each student to examine a 
number of horses in the neighborhood so as to become familiar 
with the superficial, regional diseases as they are located on various 
animals of the neighborhood. See illustration on page 455. 
3. Co-oPERATION OF LocAL VETE&RINARIAN oR Puysicran.—Ordi- 
narily, the local veterinarian or physician will gladly co-operate with 
the teacher in a laboratory period to be arranged for. Frequently 
he will be able to provide the necessary material or live specimens 
for an invaluable exercise. Under his direction the places for tak- 
ing the pulse, how to take the temperature and counting the respira- 
tions may be indicated. The facts brought out in previous lessons 
may be gone over and their practical application made interesting 
to the class. The veterinarian often has available cases under way 
that can be discussed and their treatment outlined. Teacher and 
students are urged to get in touch with the local veterinarian for the 
interesting and valuable information and suggestions that he can give. 
4. Post-MorteEM EXAminaTions.—Follow paragraphs 12, 13, 14 and 
15 in Lesson Forty-one, if an opportunity is offered for making a 
post-mortem examination. Often it is possible to arrange for such 
a demonstration with the local veterinarian. His advice and instruc- 
tion will prove of invaluable and incalculable good for all years to 
come. On nearly every farm an opportunity is occasionally offered 
for such work. No student of this book should neglect making such 
an examination whenever the occasion arises permitting him to do so. 
5. Putse or Farm AnrMAts.—The pulse of the horse is felt on 
the lower jawbone; and in the cow on the jaw, inside of the elbow 
and cannon and the base of the tail. Pulse beats vary. In the 
healthy horse the range is from 36 to 40 a minute; in the cow 45 to 
50; in the pig 70 to 80; in the sheep 70 to 75. The pulse is slightly 
slower in males than females, and is more rapid in young animals
