LIFTING is sometimes used as meaning 

 the same as transplanting, and at others 

 merely means passing the spade under a 

 plant, and, by raising it up, disturbing its 

 roots to check its luxuriance. 



LIGATURES, twisted very tightly round 

 the small branches of trees, and the 

 stems of plants, to check the return of 

 their sap, and thus promote their fruit- 

 fulness, and the size of the fruit, are 

 much to be preferred to ringing, or other 

 removals of the bark, which cause wounds 

 and canker. Ligatures should be removed 

 as soon as the fruit is ripened. 



LIGHT has a most powerful influence 

 over the health and life of a plant, from 

 the moment its leaves pierce through 

 the surface of the soil. If absent, they 

 become yellow, or even white, unless un- 

 corabined hydrogen be present, in which 

 case they retain their verdure. It de- 

 serves notice, that it has been proved by 

 the experiments of Dr. Hope and others, 

 that light from artificial sources may be 

 concentrated so as to enable plants to 

 absorb oxygen, and perfect those elabo- 

 rations on which their green colour de- 

 pends; and the light of the moon has 

 a like influence. A similar concen- 

 trated light will make the Pimpernel and 

 other flowers, which close until sunrise, 

 open their petals, and rouse from their 

 rest; a fact which gives another reason 

 why plants in rooms frequented at night 

 become weak and exhausted sooner than 

 those which remain as nature dictates, 

 unexcited by light. A deiiciency of light 

 decreases the decomposing power of the 

 leaves. For this reason the best glass 

 should always be employed in the sashes 

 of the hothouse, conservatory, and other 

 structures of the forcing department.
