some sclieme has been devised to cover them, boxes and all, with other 

 boxes or blankets. It may be noticed that peas endure the cold better 

 than beans. 



The first thing seen of beans planted in the soil, is an 



arch or ox- bow pushing its way to the light, and later, 



one end of this bow pulls up the seed-leaves back end 



first. In most cases the seed-coat was left in the soil 



where the bean was planted, but if not, then two green, 



bil^sting'^^th'rough^'the Tough, pointed leaves coming out from between the 



soil. seed-leaves pushed off the seed-coat which dropped to 



the ground.

 seed-coat. 



If we examine these green leaves we shall see that each one is folded 

 -with one-half facing the other half and then the two leaves as folded in 

 this way overlap each other. The leaves are placed opposite each other 

 and are shoved outward and upward by the growth of a short stem. When 

 several inches high, one or more pupils will discover a tender bud between 



the two rough leaves and about it are four little 

 slender pieces. Still later the leaves open more or 

 less and the lower part is seen to be in the shape 

 of a section of a heart as usually seen in drawings. 

 A pea buried in the soil also pushes up an ox- 

 bow much like that of a bean, but the seed-leaves 

 instead of showing themselves, like those of the 

 bean, remain covered where they were planted. 

 The fact is the stem below the seed-leaves of the 

 bean, between seed-le-aves and roots, grows to be 

 four to six inches high, while the corresponding 

 part of the pea fails to stretch out much, if any, 

 remaining very short, thus permitting the seed- 

 leaves to remain below. The portion of the
