WINTER WORK 



Study of soils 



Experiments on soils of various kinds may readily be made in winter ; 

 for, even though the ground is frozen, a few blows with a pick will procure 

 enough earth for use in the schoolroom. Loam, clay, sand, gravel, muck, 

 and woods earth may be tested and compared as to capacity for absorbing 

 and retaining moisture; as to the amount of air that would be permitted 

 to reach the roots of growing plants; and as to the amount of plant food 

 that these soils may contain. Discussions mav be held as to what kinds of 

 plants should be grown on these different soils and v/hat treatment should 

 be given to make some of the soils more fertile. Answers to these questions 

 may not be as accurate as a chemist would desire, but one will be able to 

 arrive at reasonable conclusions; for example, that a peaty bit of 

 muck, able to hold its own weight of water, would not do at all for a potato 

 patch, but might make a good celery bed. 



Testing seeds, and observing the amount oj plant food stored in roots, bulbs, 



and tubers 



Seeds, and roots and tubers for planting, like all living things, are likely 

 to have a more vigorous growth i they come of strong parentage and have 

 received good care. If through accident, age, or neglect they have lost 

 any part of their vitality, it pays the farmer to know the fact before the 

 time to plant. These lessons and experiments may be made exceedingly 

 interesting to children and they should be encouraged to make and keep 

 notes, which may be helpful to them later, when planting in the open 

 ground.
