CHICO FORESTRY SUBSTATION, SACRAMENTO VALLEY. 339 



The only living specimens of E. globulus stand in a much sheltered posi- 

 tion among large white oaks. They have several times suffered from frost, 

 and large branches have been killed. Under these circumstances, the 

 total growth of this species is considerably less than that of E. viminalis. 



One of the most sturdy species on the station grounds is E. eugenoides, a 

 fine, strong, upright tree, as hardy as viminalis, but of less rapid growth. 



In point of attractiveness, no eucalypt at either Chico or Santa 

 Monica surpasses E. viminalis, var. minima, a beautiful weeping tree, 

 which adds to an upright stem the charm of long, graceful, trailing 

 branches, as slender as those of the weeping willow; and has proved 

 entirely hardy here. This species should become a very popular shade 

 and ornamental eucalypt for Northern California. The small, white 

 flowers, abundant in March and April, fairly cover the tree. 



New Tests of Eucalypts. Since 1894, seeds have been sown and plants 

 raised of some thirty species obtained from the Melbourne Botanic 

 Gardens, from Vilmorin, Paris, and from the Santa Monica substation. 

 The following notes show results to date: 



Eucalyptus alpina was planted in forest in the spring of 1896. The 

 tallest tree is now 6 feet, with spread of 2-J feet. It grows much better 

 than at Santa Monica. The growth of 1897 was 14 inches. The new 

 growth of 1898 was 6 inches, when measured in May. Hardy here. 



Eucalyptus acerbula (quite rare and new to California). Planted in 

 1896. Tree a beautiful one, with remarkably fine, delicate leaves and 

 red bark. Height 2 feet in October, 1897. Spring growth of 1898, 

 1 foot. Hardy here. 



Eucalyptus gunni. Planted in 1896. Trees of 7 feet in height badly 

 frozen. The growth of 1897 was 4 feet. This species will probably be 

 somewhat hardier when large, but is of doubtful value here. 



Eucalytus ll Foeld Bay." Planted in 1896. The best tree so far tested 

 in the forest. Largest specimen, 9 feet, with 6 feet spread of bough. In 

 appearance it resembles the blue gum, but the young growth is very red, 

 and more attractive. Hardy here. 



Eucalyptus leucoxylon. Planted in 1896, when very small. Height, 

 October, 1897, 3 feet. Trees healthy and hardy here. A great acquisi- 

 tion to the district, but a grower and chiefly ornamental. 



Eucalyptus resinifera, and others. E. resinifera is very tender here; 

 only one tree is left, and shows no tendency to sprout from the base. 

 Eucalyptus rudis is also very tender here, and unfit for the district. 

 One tree of 18 inches is still struggling to recover ground. E. tereticornis 

 is another species that is too tender here, though of somewhat better 

 growth. The following species have been frozen to the ground, and did 

 not again start: E. cosmophylla, E. cinerea, E. Lehmanii, E. acmenioides, 

 E. andreana, E. botryoides, E. decipiens, E. floribunda. Adding to this 

 list E. maculata var. citriodora, E. ficifolia, and E. calophylla, which 

 have proven too tender here, either in nursery or after being planted in 

 the grove, we have fifteen species that it seems necessary to discard. 



Large Acacias. The most hardy acacias planted here some years ago 

 are A. melanoxylon and A. pycnantha. A. decurrens, the black wattle, 

 in all its varieties, while semi-hardy, and eventually making a large 

 tree, is liable to have large branches killed back. This is particularly 

 noticeable with A. mollissima, the popular street tree. A. melanoxylon 

 has not suffered seriously in twenty years of trial in the Chico region. 

 Acacia cyanophylla is only semi-hardy here.
