 needful. Such as are placed on the flues may re- 

 quire a little every day, or every two days, on ac- 

 count of their drier and warmer situation ; but all 

 the plants, in whatever situation placed, should be 

 regularly looked over, and have water, less or more, 

 as they may stand in need of it. 



Bulbous flowers in pots, as Hyacinths, Poly- 

 anthus-Narcissuses, &c. will require regular and 

 free supplies of water ; more especially those far- 

 thest advanced, and coming iritp flower. Such as 

 are in glasses, should have the water changed once 

 in four or five days, or perhaps only once a-week, 

 which must be regulated according to the state of 

 their growth ; never, however, allowing their fibres 

 to knot or cluster, which they always do, if the wa- 

 ter be not regularly changed. 



Of cleaning the Plants of Insects. 



The plants should be revised for the purpose of 

 cleaning them from dirt collected in winter, and 

 from insects ; about the middle or latter end of the 

 month is a proper time. The best way is to do this 

 individually, and not collectively, as often super- 

 ficially done, to very little purpose. It is certainly 

 better to clear the plants completely at once, though 

 it should cost a day's work or two, than to be always 

 cleaning, and still never be clear from insects of one 

 kind or other. 



Those plants which the coccus or scaly insect 

 chiefly annoys, as myrtles, oranges, olives, and other 

 hard, smooth-leaved kinds, should be carefully wash-
