38709 to 38731— Continued. 



38713. Eucalyptus cladocalyx F. Muell. Sugar gum. 

 (Eucalyptus conjuocalyj- V. Muell.) 



This tree attains :i fair size and is commonly symmetrical and 

 erect. Its growth is quite rapid from an early age. The usual 

 height ranges from 50 to 100 feet, and in Australia the trunk is said 

 to often attain a diameter of 5 or 6 feet. As a rule the trunk is 

 straight, with only a slight taper. The bark is left smooth by i In- 

 continuous flaking off of the patches or strips. The bark of the main 

 stem is usually a deep cream color, that of the branches darker 

 before shedding, and of the young twigs quite red. This Eucalyptus 

 furnishes a timber that is very durable as railway ties, as posts, and 

 for other underground situations. The wood warps very little in 

 drying and when dry is very hard. It is also useful for the naves 

 and felloes of wheels. (McClatchie, p. 57, 58.) 



38714. Eucalyptus vimixalis Labill. Manna gum. 

 Both in Australia and in the Southwest the individuals of this 



species make rapid growth and commonly become trees of large size. 

 Those growing in the Southwest give promise of eventually attaining 

 a height of 300 feet and a trunk diameter of 15 to 30 feet. The surface 

 of the bark varies considerably in appearance. That of the trunk and 

 main branches is commonly persistent, but from some trees long. 

 slender strips are shed, leaving the trunk smooth and of a greenish 

 or reddish creamy color. The persistent bark is brownish in color, 

 furrowed and rough. This bark has the peculiar characteristic of 

 exuding a honeylike substance, called ' lerp ' by the natives, but bet- 

 ter known as ' manna,' when the bark is punctured or wounded by 

 insects. This Eucalyptus grows under quite a variety of climatic 

 conditions. In the Southwest it thrives near the coast, on dry mesas. 

 in the elevated valleys of the interior, and in the hot valleys of 

 much of the desert region. The timber of this tree is less valuable 

 than most of the eucalypts. It is not durable under ground and does 

 not make good fuel. In Australia it is used for shingles and for 

 rough building material. The tree can be grown for a forest cover, 

 for windbreaks, for fuel, and for shade in many localities where 

 species producing a better timber will not grow. (McClatchie, i>. 

 82, 83.) 



38715. Eucalyptus globuli s Labill. Blue gum. 

 This species is the best known of the eucalypts and in many 



respects the best known tree in all the world. It is the third tallest 

 of the species Of Eucalyptus, the usual height in Australia being 200 

 to 300 feet. In California, where trees can be found 30 or more 

 years old. many have attained the height of 150 feet, and a diameter 

 of 3 to 6 feet during these years. This remarkable tree has the 

 power of adapting itself to a variety of Climatic conditions. It thrive- 

 both in moist, warm regions, and in quite hot, dry ones. It makes 

 a good growth both in low lands and in dry. stony uplands. This 

 species is the most generally useful of all the eucalypts. The timber 

 of this tree is of a rather pale color, is hard, heavy, and very strong 

 and durable. It is fairly straight grained and split - easily. In 

 Australia it is used for shipbuilding, for carriage making, and in 

 the manufacture of agricultural Implements. It is also used in
