National Garden at Paris, and has since yielded in several other establishments 
of this country. The Chatsworth specimen is planted out in the large conservatory, 
a short distance from the flue, which passes beneath the boarded walk on the 
western side of the house ; from this position it is probable that some degree of heat 
may more or less affect the roots ; in other respects the situation is a cool one, being 
but a short distance from the part occupied by Seville oranges, and other plants 
requiring similar temperature. 
Our observations of its habits have led us to the conclusion, that a very moderate 
heat is far more beneficial than the high temperature to which it is in most places 
exposed. If subjected to the latter treatment, it soon becomes covered with aphis, 
and filth upon its leaves, even though often washed with the syringe. 
It must be remembered that however injurious insects are to vegetation, they 
rarely if ever, are the primary causes of disease ; their attacks always indicate some 
previous internal interference with the natural functions of the plant, by which the 
juices are to a certain extent changed, and thus become suitable food for these 
creatures, which immediately begin to deposit their eggs. When hatched they feed 
upon the juices of the plant, and thus increase the original disease. If these attacks 
are of long continuance, unless some foreign aid is administered, the efforts of 
nature become too enfeebled and paralysed to enable the plants to recover, for that 
season at least, their usual health and vigour. This subject, however, we can only 
at present touch upon, and must waive our remarks to a future day, and return to 
the treatment of the Jamrosade at Chatsworth. 
It requires a large surface of soil for its roots, which grow strong and spread 
to a considerable distance. The soil in which it is planted is a rich but sandy loam. 
During the season of growth it is syringed freely every fine day, and also receives 
a good supply of water at the roots ; but during the time when the blossoms are 
expanded, and the fruit setting, syringing is altogether dispensed with ; but is resumed 
again as soon as the fruit begin to swell. It is rather a quick growing tree, if kept 
clean ; our plant is already 15 or 16 feet high, and spreading in proportion, although 
still quite young. 
The inflorescence is produced in cymes, each containing five or more flowers, 
but sometimes from abortion only two. The cymes spring chiefly from the axils 
of the leaves, on the previous year's wood, but occasionally they are terminal on the 
young growing shoots of the current year. 
The flowers appear large in size on account of the long filaments, which are very 
numerous and spreading ; both these and the small petals are white when they first 
open, but slightly change to a pale yellow before they fall. 
The fruit at first swells slowly until syringing is resumed, then if the plant be 
subjected to a genial warm and moist temperature, they show signs of rapid progress, 
and become fully swelled and ripened by the end of July. 
The flavour may be likened in some degree to an inferior orange apricot, and the 
fruit is about the same size ; it possesses, however, the fragrance of a rose in a
