CIVIC lilOLOGY 



Nut trees. Hie rocky hillsides of Italy and Spain, planted 

 to chestnuts, are said to produce witliout labor as valuable 

 crops as our own best Avheat lands. We are importing annu- 

 ally over 114,000,000 worth of nuts. How many, even then, 



have all the nuts they 

 want ? 



Make careful collec- 

 tions of all the differ- 

 ent nuts in the district 

 and prepare them for 

 exhibition in class, keep- 

 ing records of trees that 

 produce the best. Pre- 

 serve as many as pos- 

 sible of the best for 

 planting, exchange with 

 other schools, and ar- 

 range, if possible, to buy 

 seeds or j^oung trees, or 

 obtain scions from the 

 best varieties of pecan, 

 hickory, A\aliuit, and 

 chestnut that can be had 

 from anv ])art of the 

 country. Organize ex- 

 hibits of nuts in connec- 

 tion with local horticultural fairs. I^y these means we may 

 improve quality and increase yield of mits to any desired 

 amount. At the same time the wood of our native nut trees, 

 • — hickory, black walnut, chestnut, — for certain uses, is the 

 best we can grow.

 method each tree has developed for scattering and planting its own seeds.
