and fifty of the dragon's-blood tree (Draccena draco), about 8 

 feet in height. All the trees were, in December last, in full 

 flower or fruit. Among the more remarkable of the smaller 

 avenues is one formed of bamboo (JBambusa arundinacea), 

 planted in 1863, and forming an immense mass of foliage, the 

 stems supporting which are from 40 to 50 feet high ; and an- 

 other formed of about one hundred plants of Chamwrops ex- 

 celsa, each being about 10 feet in height; other palms which 

 flourish to perfection are Caryota urens and C. Cumingii, 

 growing 15 feet high and covered with fruit; Oreodoxa regia, 

 from Cuba ; several plants upward of 25 feet in height, and 

 a plant of Juboa spectabilis 12 feet high. There is a small 

 forest of Anona cherimoya in full fruit, which is nearly as 

 good as that of the closely related species which yields the 

 custard-apple. Near this is an immense tree, some 30 feet in 

 height, covered with fruit of the Avocado pear (Persea gra- 

 tissima), and at its feet a quantity of guava-trees (Pisidi- 

 um cattleyanus) crowded with its perfectly ripe, large, pear- 

 shaped, golden fruit. In the New Holland district of the 

 garden are different species of acacia, many of them 20 to 25 

 feet in height, and magnificent trees of several genera of Pro- 

 teacese, Banksia, Jlokea, and Grevillea / and trees of Euca- 

 lyptus globulus planted in 1862, and then only a few inches 

 high, which are now about 40 feet in height, and over 4-J feet 

 in circumference. There is a specimen of Araucaria excelsa 

 about 60 feet high, and measuring a little over 9 feet in cir- 

 cumference at its base. 



SUB-TROPICAL GARDENING IN" ENGLAND. 



One of the most successful attempts at sub-tropical garden- 

 ing in En 2f land is on the estate of Mr. Robert Were Fox, F. R. 

 S., at Penjerrich, near Falmouth, in Cornwall. The tempera- 

 ture is here extremely mild in winter, the thermometer never 

 falling below the freezing-point for more than two or three 

 nights in succession, and hardly ever below 30 F., and snow 

 never lying on the ground. Many trees and shrubs which 

 are only seen in hot-houses in other parts of England here 

 grow to perfection out of doors. The hydrangeas, covered 

 with magnificent masses of blue flowers, here form splendid 

 banks by the side of a stream running through the grounds, 

 the small lakes in which are covered with several exotic spe-
