It will be of importance always to have the water 
made a little warm, previous to its being' used, in 
the winter and spring, viz. from 60 to 80 degrees, 
and also when the weather proves cold in the 
summer, for the application of cold water, to plants 
tenderly nursed, must naturally produce a sudden 
tr.ansition in the state of the sap. The quantity 
of water necessary for these plants, will of course 
vary materially, according to the state of the 
plants, beds, weather, and nature of the soil ; 
but, unfortunately, it is a rule with some growers, 
to use a regular quantity of water, whether the 
bed on which the Plants grow is hot or cold, or 
the atmosphere bright or cloudy. No exact rules 
can be laid down for the process of watering, as 
it will be very much affected by circumstances ; 
and nothing but practice can give the learner 
the proper knowledge. I may, however, venture 
to suggest the few following' remarks, which, I 
trust will afford some useful information to young 
practitioners. 
While the Plants are remaining in the pots, 
where they were first sown, if the bed should not 
be of sufficient heat, and the weather dull or 
cloudy, especially if the Plants are crowded, no 
water should be applied, till the moment they ai'e 
about to be removed into other pots, as they are 
liable to decay or damp if near the surface of the 
earth. Those Plants, from the time of their first 
removal into the nursery pot, are subject to the 
Canker, in stagnant beds deficient in heat, and
