It appears therefore from this, and the two preceding ex- 

 periments, that the same degree of temperature, which may 

 promote the growth, and exuberant health of the plant, may, 

 at the same time, render it wholly unproductive of fruit or 

 offspring. 



The Fig Tree. Several varieties of this species were sub- 

 jected to experiment ; but the trees, although planted in 

 pots, grew with so much luxuriance, and afforded me so 

 little prospect of fruit, that I removed all except those of the 

 large white variety, from the house. The White Fig tree 

 succeeded perfectly, first ripening its spring-figs, (those 

 which usually ripen in the open air in this country,) and 

 afterwards its summer figs. The trees then produced new 

 leaves and branches : and the fruit, which would have 

 appeared in the next spring, ripened in high perfection in 

 September. Subsequently also a few of those, which, in 

 the ordinary course of the growth of the tree, would have 

 appeared as the summer crop of next year, have ripened, and 

 these, though far inferior to those of the preceding crops, 

 have not been without merit. 



The Nectarine. A seed of this species of fruit was plan- 

 ted in a hot-bed, in January last, and it vegetated in the 

 succeeding month. It was subsequently removed to the 

 hot-house, in which it continued to grow through the summer, 

 without being in the smallest degree drawn by the high 

 temperature in which it was placed : its wood, on the con- 

 trary, is remarkably short-jointed, and is covered with blos- 

 som-buds ; from which I think it will be practicable to ob- 

 tain ripe fruit, within sixteen months of the period, at which 

 the plant first sprang from the ground.
