LESSON II. 
Subject. — Harvesting and grading potatoes. 
Problem. — To study the farm practice in harvesting and grading 
potatoes with a view to finding the most efficient methods of handling 
the potato crop. 
Sources of information. — Farmers' Bulletin 753 ; Document, Mar- 
kets, 7; circulars and bulletins from State college of agriculture; 
articles in the farm papers. 
Class exercise. — The application of this subject to the seasonal 
practice of the district and to the projects of the pupils will call for 
modifications to suit each case. Late potatoes are harvested in the 
Northern tier of States from the latter part of August to the middle 
of October. In the Northern States the main crop is planted during 
the summer and the harvest begins after the middle of October. In

observe or participate in the harvesting and grading soon after the 
school work in the same subject. The following items of farm prac- 
tice in the handling of potatoes should be noted :
