of roads is the next topic of importance introduced to the students, Financial benefits, cost of transportation, the influence upon markets, and social benefits are thoroughly explained in the new course. They also learn that good road is one over which travel may take place with ease and com fort and one over which freight or pro- duets may be hauled at a low cost Good roads must not cost more than q certain amount. or the value of it's ser l vices will not cover the interest on the investment. The total mileage of roads in the United States is about 1000. 900 miles. This will give the members in- ] terested in the course a large field to ! work in. If they learn all the wisdom | that farm engineering teaches, fortunes stare the ardent workers in the face i The classification of roads is a very i essential point to the student There are clay roads, sand roads. and gravel roads and they must learn how to treat each case.
 Farm Machinery
 Four requirements for any satis- factory machine are taught the student. For instance, a harvester must cut the standing grain and bind it into bundles | with never failing accuracy Second. the machine must do it's work effi- ciently; third the parts of the machine | must be strong enough to resist breakage; fourth. the machine must be durable. This is the most practical part of the course. Engines of every prominent make will be assembled and disassembled by the students. Mir Gambel is an engine specialist anc what he doesn't know about machinery
 few engineers know. But the visitor , on seeing the different parts scattered
 here and there would have the notior
 that the students were fixing the en. zine so that nobody else could This i.
