b l 24i APPENDIX. 



The bulbs having, at that season, pushed out their roots 

 to the depth of 16 or 20 inches, their extremities become 

 immersed continually in water, which, by fault of a descent, 

 to occasion its running off, joined to the little transpiration 

 the vegetable world has during the winter months, causes 

 the roots to putrefy, and communicates a disease to the bulbs, 

 which totally destroys them, or at least renders the flower 

 poor and small. The bulbs become thin, and when taken 

 up, they will be found shrivelled, and all in scales. 



To prevent this misfortune as much as possible, we would 

 advise those amateurs, in cases of heavy rains, or melting 

 snows, to give a vent to them, by either making small de- 

 scents to drain them off, or rather to have small trenches dug 

 round the beds, as we have already mentioned, and to be par- 

 ticularly careful to raise the beds at least 7 or 8 inches above 

 the common paths. 



Of Evaporation. — The bulb of the hyacinth is succulent 

 and full of sap, which is the reason that for want of due eva- 

 poration it very easily putrefies, — a misfortune which we must 

 endeavour to prevent as much as lies in our power. To 

 prove that the bulb abounds with rich juices, take eight or 

 ten roots at the time of transplantation, or rather the time of 

 taking them up ; they will perhaps weigh 1 lb. Three weeks 

 after having lain on the shelves, you will find they will only 

 weigh 12 oz., so that they will have evaporated one-fourth 

 part in that space of time. 



These vapours being condensed either in the room or in 

 deep drawers, in which they may be laid to dry one upon the 

 other, have the same pernicious effects as the wet and mois- 

 ture in the ground has, when it is not made to be drained 

 off; that is to say, it occasions putrefaction, and totally de- 

 stroys the bulbs. 



The place destined for the reception of the bulbs, after 

 taking them up, ought to be vciy dry. For this reason, 

 greenhouses which are naturally placed to the south, are 

 preferable to any other place. 



The windows should be open on all sides, or at least on 



or three, that the air may have a {rvc passage, especially 



during the fir ' I the bulbs have been there
