with it ; for, soon after being put out, most of the leaves fell off, 

 and those which remained, as well as the ends of its branches, 

 turned yellow ; a plain indication of its sufferings from the cold 

 nights. Nevertheless, the great heat of our Paris summer soon 

 restoring it to its ordinary vigour, numerous young shoots, and 

 many flowers pushed out, but they fell off without producing 

 fruit. In this way, I persisted to cultivate this tree till last 

 spring (1801), being anxious to try, if in so many years it might 

 not be habituated to our climate; but it annually underwent the 

 same alteration of sickness and health already detailed.* 



At this period, wishing to make it produce fruit, I thought all 

 that might be necessary would be a large portion of air with very 

 great heat. For this purpose, it was left in the great stove at 

 the foot of a very white wall, which by reflecting the rays of the 

 sun, increased the heat still more, and the tree was so placed as 

 to receive the rays perpendicularly. The air was suffered to blow 

 freely round it, and it was deluged with water, in consequence 

 of the great evaporation produced by so much heat and air. 



My wishes were thus completely fulfilled : the tree grew most 

 luxuriantly, being covered in June with numerous flowers, which 

 were rapidly fecundated, the greater part of them being suc- 

 ceeded by ripe fruits, of which I gathered more than forty. Some 

 of the finest are preserved in the gallery of Natural History ; of 

 others which fell off, I have already sown the seeds : and others 

 still on the tree, will be suffered to remain till they drop off 

 spontaneously, that I may be quite certain their seeds are per- 

 fectly ripe. From an examination of the kernel, which soon 

 changes to a hard horny substance, it is not surprising, that all 

 the seeds imported from abroad have hitherto failed, unless they
