The oOicial journal of the Kansas Agricultural College, The Indus- 

 trialist, has been running two special series, one a farmers' institute 

 series, with practical suggestions for adult farmers, the other an agri- 

 cultural education series, with lessons for teachers and pupils on such 

 subjects as how plants feed and grow, plant breeding, a corn primer, 

 tree culture, the soil, an elementary study of insects, and insects inju- 

 rious to farm crops. 



The extension bulletins of the Ohio College of Agriculture have 

 appeared at frequent intervals with special school articles on such 

 interesting and instructive topics as the horse, our useful birds, the 

 preparation of the seed bed, propagation of plants, tillage and culti- 

 vation, what trees do, the story of the life of a moth, sheep, and what 

 makes the wnnd blow. 



From the agricultural department of Miami University, Oxford, 

 Ohio, have come two useful school bulletins: The Soil and Its Rela- 

 tion to Plants, and Experimental Studies of Ptant Growth. 



The New Hampshire college has started a series of school bulletins 

 wuth suggestions for teachers of elementary agriculture. 



The New York State College of Agriculture has continued its 

 Home Nature Study Course circulars for teachers and its Rural 

 School Leaflet for teachers and pupils. The latter is said to have 

 reached 75,000 pupils in 1909, with helpful lessons on plant food, the 

 horse, poultry, dairying, and other related topics. 



The Hampton leaflets have appeared as usual, with occasional num- 

 bers dealing w'ith special elementary lessons in agriculture. Three 

 such lessons appeared during the year: The story of corn, plowing 

 and harrowing, and culture and marketing of tobacco. 



COLLEGE EXTENSION AND SHORT COURSES. 



All forms of agricultural extension work have developed rapidly 

 during the year, and as a result of increasing demands upon the 

 agricultural colleges for itinerant instruction and demonstration, 

 many of these institutions have organized and manned extension 

 departments. Some of the features of school extension w^ork are 

 described briefly in this report (pp. 317, 322), but a more extended 

 account of them is given in the report of the farmers' institute spe- 

 cialist, on page 327.
