shred envelops the branch, the wood 

 beneath is never so well ripened as 

 those parts' exposed to the light and 

 air, which are so essential to enable 

 the bark to assimilate and separate 

 from the sap those secretions which 

 are required for the next year's growth. 

 Shreds should always be long enough 

 to permit the ends to be doubled over, 

 so that the nail may pass through four 

 thicknesses of the cloth, otherwise they 

 look ragged and are liable to tear away 

 from the nail. If old shreds are re- 

 used, they should be previously boiled 

 for a few minutes to destroy any insect- 

 eggs, or larvae they may contain. 



SHRIVELLING of the berries of the 

 grape in stoves arises from the roots of 

 the vine not supplying a sufficiency of 

 sap. This occurs if the roots are in a 

 cold heavy soil, or are vegetating in an 

 outside border, the temperature of which 

 is too low compared with that of the 

 stove. In the first case, thorough 

 draining and the incorporation of cal- 

 careous rubbish; and in the second 

 case, protection to the border and stem, 

 will remove the evil. 



SHRUBBEEY is a garden, or portion of 

 a garden, devoted to the cultivation of 

 shrubs. 



SHRUBS are trees of a dwarf growth, 

 not exceeding in height twelve or fif- 

 teen feet, unless they are climbers, and 

 having, if permitted, branches and 

 foliage, clothing the entire length of 

 their stems.

SHUTTING-UP is closing the lights of
