7. Do I understand the important market classes and grades of 
wool ? 
S. Will it pay as a rule to sell the wool at shearing time or hold for 
higher prices? 
CLASSROOM INSTRUCTION. 
Use of reference material. — Although most of the general textbooks on animal 
husbandry deal with sheep, none of them treat the subject as extensively as 
may be desirable in a section especially favored for sheep. While the special 
- on sheep are best suited to such special courses as are given in colleges, 
one or more of these books should be included in the high-school library to be 
used for reference purposes. The publications of the Department of Agricul- 
ture listed at the end of this document will serve well for the class and for 
special assignments to individual students. A number of the State colleges 
have issued excellent expository bulletins on sheep, which should be used in 
adapting the instruction to meet local conditions. 
Although the project study outline given on the preceding pages is intended 
primarily to guide the student who has a project in making an individual study 
of the subject, it should be suggestive of a general consideration of the subject 
in the classroom. For a comprehensive reference for the subject, one that may 
serve as a text, Department Bulletin 20, The Management of Sheep on the Farm, 
is recommended. Farmers' Bulletin 840, Farm Sheep Raising for Beginners, 
will also serve well for the same purpose if supplemented with the following 
Farmers' Bulletins: 652, The Sheep-Killing Dog; 713, Sheep Scab, and 810, 
Equipment for Farm Sheep Raising. 
Z~se of illustrative material. — The work of the classroom will lack vitality if 
it is not connected very closely with the practical work of the students and 
with the sheep industry of the community. The instructor with the aid of the 
students should make a survey of the district with regard to its sheep interests 
as a means of knowing the practices common in the section and of locating ma- 
terial to be used in teaching. Field trips should be planned for the purpose of 
bringing the students into close touch with the methods of the best farmers as 
well as to give them practice suggested previously. Inasmuch as the very best 
stock is often sent to the fairs, the teacher should seek opportunity to visit 
them with his students for the definite purpose of seeing good stock and getting 
in closer touch with the best breeders and judges and learning something of 
their methods. In connection with a study of market demands and methods of 
shipment visits should also be made to packing houses and shipping points, if 
such are convenient. If this department or the State college has established 
demonstration sheep farms near the school, it should be used by the class. 
Although all schools will not be favorably situated with regard to good 
sheep farms and fairs, all teachers will be able to secure good illustrations to 
aid in visualizing the lessons given. Illustrations from the best papers and 
catalogues should be supplemented with charts and blackboard illustrations 
showing the conformation of types and naming of parts of animals in connec- 
tion with judging, and plans of buildings, pens, and other equipment in connec- 
tion with management. Along with a study of wool, samples from the various 
types of sheep taken from different parts of the body should be collected to be a 
part of the permanent school exhibit. It may be possible to secure from manu- 
facturers samples showing market grades and classes of wool, and the steps 
represented in its manufacture into yarn and cloth. 
II. GOATS. 
POSSIBILITIES IN GOATS. 
The present shortage of milk and the national movement to utilize all the 
land possible for food production is bringing the attention of thoughtful people 
to the possibilities in milk goats. Thousands of acres of vacant lots in and 
near our American cities and great tracts of unused land in the country 
might support goats which would in many cases supply a need for milk which 
at this time is acute among the poorer classes. A good goat will furnish fresh 
milk for a family which could not afford to keep a cow, and in many cases live 
on laud and forage that would otherwise be wasted. The lives of many infants 
might be saved if a fresh supply of goats' milk were available. Although the 
American people are awakening to an appreciation of milk goats, the greatest
