Bulbous flowers in pots, as Hyacinths, Polyan- 

 thus-Narcissuses, &c. will require regular and free 

 sup})lies of water ; more especially those farthest 

 advanced, and coming into flower. Such as are in 

 glasses, should have the water changed once in four 

 or five days, or perhaps only once a-week, v;hicli

 growlh ; never, however, allowing their flbres to 

 knot or cluster, which they always do, if the water 

 be not regularly changed.

The plants should be revised for the purpose of 

 cleaning them from dirt collected in winter, and

 individually, and not collectively, as often super- 

 licially done, to very little piu'pose. 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 

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