in the case in which they we^e imported until they began to grow ; after 
that they were potted in turfy loam and white sand, well drained, and were 
plunged into a bark bed. When they became too tall for that situation, 
they were removed to the tropical-house, where they increased rapidly in 
size, making two growths regularly every season. They were shifted into 
larger pots or tubs as they appeared to require it, until about three years 
ago, when the plant now bearing fruit was placed in a tub three feet square, 
and his Grace the Duke of Northumberland, thinking it had become large 
enough to fruit, caused a partition to be made in the tropical-house and a 
space to be wholly set apart for the Mangosteens, in which bottom-heat of 
from 80° to 90° could be maintained by means of hot-water tanks running 
alongside the tubs in which the largest plant was growing, and the soil in 
which another was planted out. An atmospheric temperature, ranging from 
65° to 90°, was at the same time kept up, together with a continual supply 
of fresh air from cold air drains which crossed the house, and discharged 
themselves amongst the hot-water pipes at the back, on which water in pans 
kept continually evaporating abundance of moisture. Under these con- 
ditions, and by means of shading in bright weather, and giving plenty of 
water when the plants were growing, they made a most vigorous growth 
two years ago, since which time they have apparently been preparing for 
flowering, having only made one growth in a season with much shorter- 
jointed wood and smaller leaves, and the shoots which have now produced 
flowers have remained stationary since last October twelvemonth. The first 
flowers expanded on the 18th of November last; the petals fell off the 
following day, and the fruit, which almost immediately began to swell, is 
now the size of a Greengage Plum, with every appearance of arriving at 
perfection. At the present time there are four fruit swelling, and one 
flower has been taken off for botanical examination. The plant is about 
fifteen feet high, nine feet in diameter, and the stem six inches in circum- 
ference. The flowers were about two inches in diameter, and the petals 
brownish red shaded with yellow." 
Whether these fruits will prove to have really set is uncertain. When 
the flowers expanded the anthers appeared to be destitute of pollen ; a camel- 
hair pencil was, nevertheless, drawn carefully among the anthers, and then 
applied to the stigma, in the hope that a few particles of pollen might 
lurk among the anthers, although invisible to the eye. Possibly this was 
the case ; possibly the fruit was set before the flowers expanded ; possibly 
the fruit may still drop off. But, in the meanwhile, we are informed that 
it presents no symptoms whatever of being otherwise than in the most per- 
fect state that could be desired. — G-ard. Chron.
