2 BULLETIN 763, U. S. DEPARTMENT OF AGRICULTURE. 
one or more bulletins on some phase of dairying, and in most instances 
these may be had for the asking. Address the dean of the agricul- 
tural college. 
The Farmers' Bulletins of the United States Department of Agricul- 
ture referred to in this bulletin will cover most of the topics to be 
studied. Bulletins in this list will be sent free, so long as the supply 
lasts, to any resident of the United States, upon application to his 
Senator, Representative, or Delegate in Congress, or to the Chief of the 
Division of Publications, U. S. Department of Agriculture, Washing- 
ton, D. C. Because of the limited supply, applicants are urged to 
select only a few numbers, choosing those which are of special interest, 
and ordering but one copy of each. When the free supply has been 
exhausted, a number are yet for sale. Apply to the Superintendent 
of Documents, Government Printing Office, Washington, D. C, who 
has these bulletins for sale at 5 cents each. Other publications of 
this department are for sale by the Superintendent of Documents, 
but these are more often technical bulletins, and of interest to those 
only who wish to specialize in the subject. 
Frequently revised classified lists of department publications on 
different phases of agriculture, one of which is on the subject of dairy- 
ing, are issued by the Division of Agricultural Instruction, States 
Relations Service, U. S. Department of Agriculture, for teachers' use. 
The teacher will find that a number of the textbooks on dairying are 
suited to her needs, and that some of the elementary textbooks may 
be used by the pupils. Dairy cattle breeders' associations and dairy 
equipment concerns publish some interesting literature that may 
be had for the asking. Usually one or more dairy journals will 
be taken in the community, or a general farm paper with a well 
edited dairy section. Pupils should be encouraged to bring these to 
school. Clippings may be made of articles of interest and filed care- 
fully. An easy and effective system of filing is to use pasteboard 
cases, which may be purchased or made by the pupils from paste- 
board boxes, and to file the bulletins in these boxes by subject. 
In addition to the Farmers' Bulletins and other Department Bul- 
letins, the Dairy Division, Bureau of Animal Industry-, issues a num- 
ber of circulars on various phases of dairying which may be obtained 
directly from that division. 
THE SURVEY. 
One of the means by which the teacher may become informed about 
the dairy interests of the district is a dairy survey. The pupils may 
assist in obtaining this information, but a first-hand knowledge ob- 
tained by the teacher will be a valuable aid. 
This survey should include the kind of farm (crop or stock farm), 
purpose of dairy cows (commercial or home use), breed of cattle,
