3. Hand tools. 
Illustrative material. — Catalogues of implement dealers. 
Exercise 1. — A Study of Tillage Implements. 
The class may spend the time profitably making a first-hand study 
of the tillage implements on a well-equipped farm or at an implement 
dealer's. This exercise should involve the naming of parts as sug- 
gested in Exercise 23, Farmers' Bulletin 638. 
Lesson 6. — Fertilizing Machines. 
1. The manure spreader. 
2. Machines and devices for spreading commercial fertilizers. 
3. Lime-spreading machine. 
Special reference. — Farm Methods of Applying Land Plaster in Western Oregon 
and Western Washington, Bureau of Plant Industry Circular 22. 
Exercise 2. — Study and Use of Manure Spreader. 
Arrangements may he made with a near-by farmer so that the stu- 
dents not familiar with a manure spreader may have an opportunity 
to operate one. . 
Lesson 7. — Planting Machines. 
1. Grain drills. 
2. Hand drills and seeders. 
Exercise 3. — Study and Use of Grain Drill. 
Students who have not used a grain drill should be favored in this 
practice to be secured on a neighboring farm if the school does not 
own one. This exercise also may involve the calibration of the grain 
drill as suggested in Exercise 29, Farmers' Bulletin 638. 
Lesson 8. — Planting Machines — Continued. 
1. Corn planters. 
2. Potato planters. 
3. Miscellaneous planting devices. 
Exercise 4.— Study and Use of Corn-planting Machines. 
Each student should be given an opportunity to become familiar

Farmers' Bulletin 638, Exercise 28, Corn Planter Operation. 
Lesson 9. — Hay-making Machines. 
1. Mowers. 
2. Rakes and tedders. 
3. Loading, stacking, and storing devices.
