382 HEARINGS BEFORE COMMITTEE ON AGRICULTURE. 
tens of thousands of farmers; and here is just what I found, as an illus- 
tration, as I imagine, of the work which the doctor is endeavoring to 
do. Governor Hoard is a specialist in talking about dairy cows and 
beef cows; and he had prepared, because he had enough interest in it 
and sufficient means, a number of oil paintings, crude, perhaps, but 
still as large as that map, giving different types of cows, the dairy cow 
and the beef cow, and dian of course, illustrating the different breeds, 
Of course that is very useful in a practical demonstration to a farm 
audience, where you are trying to impress upon them what the real 
dairy cow is or what the beef type is. That also extends to other 
fields, such as sheep. Not only that, but Professor King, down here, 
when he was lecturing in our institutes upon the subject of farm 
buildings, which is a very practical and important subject, would 
illustrate his lecture very effectively by the use of charts, and in fact 
he really required them. Then the charts which show the composi- 
tion of feeding stuffs can be made quite impressive when properly 
prepared. These individual workers, working in the States for small 
salaries, of course are not always able to obtain these things in the 
best form. I imagine the object of the professor in this matter and 
of the Department would be to supply all these institute workers to 
as great an extent as possible throughout the country with illustra- 
tions of that character, which would be in the best form. Is that 
correct, Professor? 
Doctor Trust. Yes; that is it. 
Mr. Haucen. I understood you to say there are thousands of these 
lecturers in this country. 
Mr. Apams. Oh, no. 
Mr. Havucen. I understood you to say there were a number of thou- 
sands of lecturers. 
Doctor Trur. The number of regulary employed lecturers is about 
900. Then, there are besides that several thousand local men who 
occasionally lecture. 
Mr. Havucen. Would you undertake to supply all of them? 
Doctor Trur. Certainly not. We are not asking for money enough 
to do any very large thing. 
Mr. Bowrz. You just want to pick out a few? 
Doctor True. A few of the best things and use them in the best way. 
Mr. Haucen. But that would practically lead up, would it not, to 
lantern slides for every lecturer? It would not do to discriminate, 
would it? 
Doctor Trux. It would not be our idea to give these lantern slides 
away. It would be simply a matter of loaning the lantern slides, so 
that the same lantern slides might be used ultimately in every State 
of the Union. 
Mr. Haven. Every lecturer would want to use them, and you 
would have to have them, would you not, in order not to discriminate? 
Mr. Burtxson. They could be used like a circulating library. 
Mr. Lortmer. How many slides would you use in each Jecture? 
How many would they average? , 
Doctor Truz. From 30 to 50, I should say. 
Mr. Lormenr. Are they plain or colored slides, or both? 
Doctor Trur. We would use both at times, but mostly plain slides. 
Mr. Lorimer. A set of slides for a lecturer would cost about $10.
