ed in pots so deep or large as here specified ; but in 

 such, and especially if put into ikie rich mould, they 

 flower very strong and full. It may be observed, 

 that the jonquils, both double and single, should be 

 kept two years in the pots, as they do not flower 

 well, if at all, the first season. It is therefore ne- 

 cessary to have as it were a double stock of them 

 on hand j potting a certain number of roots every 

 year. 



These roots are generally placed under the stage 

 in the green-house after potting, and are taken into 

 various forcing-houses, as above noticed, in classes or 

 divisions ; so many every three or four weeks, in or- 

 der to bring them into flower in regular succession. 

 I have no objection to their being placed under the 

 stages, or in any other situation in the green-house, 

 provided care be taken to keep them moderately 

 dry, and to keep them free of spilt water, or drops 

 from the other plants, by which they are often much 

 injured. It is a better method, however, to plunge 

 them in a cold pit or frame, among a little dry-bark 

 or saw-dust, or in a mixture of these with sand ; 

 where they can be properly attended to, and car* 

 be defended from too much wet, or severe frost,

Of the Temperature. 



In fresh weather, so long as the mercury stands 

 as high as 40, fire-heat will be unnecessary ; but 

 when it begins to fall much below that point in the 

 night, and when the frosts commence, which they
