Eucalyptus 



1619 



Mr. Robert Birkbeck, to whom we are much indebted for information concerning the 

 cultivation of this genus, has tried forty or fifty species at Kinloch Hourn, on the west 

 coast of Scotland, and sums up his experience as follows: " E. vernicosa is the 

 hardiest of all the species ; E. Gunnii, E. coccifera, E, cordata, and E. urnigera may 

 be considered quite hardy ; E. globulus will stand 15 of frost only ; and E. amygdalina 

 about the same. Both E. viminalis and E. paucifiora are more tender than 

 E. globulus. E. alpina is slightly hardier, but is killed by 20 of frost." Mr. 

 Birkbeck gives a long list ' of species which completely failed at Kinloch Hourn, 

 and tells us that E. alpina, E. amygdalina, E. viminalis, and E. globulus were killed 

 at Inveraray. 



At no place have more species been tried in the open air than at Lady 

 Ilchester's garden at Abbotsbury, in Dorsetshire ; and Mr. Kempshall, head 

 gardener there, sent us a list of forty species, all of which succumbed in the cold 

 winters of 1907 and 1908, except the following : E. coccifera, E. cordata, E. Gunnii, 

 E. Muelleri, E. vernicosa, and E. urnigera, the last named being in his opinion the 

 hardiest species. 



Mr. Birkbeck gives the following rules for their propagation and planting : 

 Raise them from seed under glass ; pot when 2 or 3 in. high ; repot often as they 

 never do well after their roots are pot-bound. Give them some bone-meal, keep 

 under glass till 3 ft. high, and plant out in good soil in May or June, when they are 

 about two years old. Keep them well staked, as they are easily blown down, but 

 keep the fastenings loose, as they increase in girth quickly. 



When planting has to be done on a large scale, seedlings should be treated 

 exactly like pines and other conifers, i.e. they should, when about 6 in. high, be 

 transplanted in the nursery to promote the formation of lateral rootlets, which will 

 render easy their establishment in the ground where they are to remain permanently. 

 Seedlings should not be dried up when being moved, and ought to be transplanted 

 in cool cloudy weather, and watered for some days afterwards. 



With regard to economic planting of the Eucalypti in warmer parts of the 

 world than our own islands, we cannot enter into any details concerning the selection 

 of the proper species ; and must refer our readers to the excellent papers of Naudin, 2 

 which deal with their cultivation in the south of France, and to those of M'Clatchie 2 

 and Ingham, 2 which give a complete account of the results already obtained in 

 California, where many species have been tried. The admirable report 3 on Cyprus 

 by Mr. D. E. Hutchins, whose long experience in South Africa enables him to 

 speak with authority, may also be consulted. (H. J. E.) 



1 A list of thirty-five species tried at Kinloch Houm is given in Trans. Bot. Soc. Edin. xx. 525 (1896). Mr. Birkbeck 

 wrote a further account of his experience in Card. Chron. xxv. 84 (1899).

 cultivation.
