 from wiiieh strips t)f bari< had been reniove<l tlian from the control trees, and the 

 experiment from this standpoint was a failure. However, the removing of the strips 

 of bark appeared to have a very stimulating effect on the growth of the main root in 

 particular and the whole root system in general. The top growth of the trees where 

 2 strips of bark had been removed averaged 44.7 ft. When one strip of bark was 

 removed the top growth averaged 3(3.1 ft. With the control trees the top growth was 

 but 23.9 ft., and the root system graded l)ut 62, as compared with a grade of 82 and 

 89 for the trees from which strips of bark had been removed. 



The notes on orchard cover crops have been abstracted from another source

Biennial report of the State board of horticulture ( [Jtali State Bd. Hurt. Rpt. 

 1901-2, pp. 69, ph. 16). — This report contains an account of the work of the State 

 board of horticulture in investigating the horticultural work of the State for the 2 

 years 1901-2. It has been definitely determined that fruit trees, when properly 

 pruned and scraped and then given 2 thorough applications of a lime, salt, and sul- 

 phur mixture, may be completely freed from the San Jose scale. W^ith trees more 

 than 30 years old, however, it has been found cheaper to cut them out than to 

 attempt to spray them. It is not deemed practicable nor advisajjle to attempt to 

 fumigate trees in combating the San Jose scale, since the lime, salt, and sulphur 

 treatment is e(]ually effective and costs only about a fourth as much. 



Investigations on the codling moth appear to indicate that there are no distinct 

 broods of the worms, but that hatching is continuous after the temperature reaches 

 65° F. at night. In order to control this pest, therefore, spraying at least once everj' 

 20 days throughout the season after the blossoms fall is advised. From 80 to 95 per 

 cent of apples free from worms have been obtained by careful attention to spraying. 



An account is given of the work and expenditures of the experiment farm for 

 1901-2. The farm is designed as a model, as well as for experimental purposes. 

 Some of the canning factories of Utah are described, and an account given of the 

 work they are doing. Pear blight has been controlled in some of the orchards 

 reported on by constant attention to the pruning out of infected parts of the tree. 

 A number of miscellaneous recommendations are made regarding the culture of fruit 

 in Utah, and spraying for the control of insect pests and the diseases of fruit trees. 



Report of the fruit expert, W. J. Allen {Agr. Gaz. New South Wales, 14 {1903), 

 No. 9, j)p- SI 1-847). — This report deals with phenological data and descriptions of a 

 large number of different kinds of fruits grown at Wagga, Hawkesbury, Bathurst, 

 Moree, Peral)ore, and Wollongbar orchards. Nearly all kinds of temperate and sub- 

 tropical fruits are considered. In a 3-years' trial of ringing Zante currants, especially 

 good results were obtained during the first 2 years, which appeared to be favor- 

 able seasons for the jsractice. The third year, however, the practice resulted very 

 disastrously; the vines set no fruit, and in a few cases died, and on the whole it 

 greatly weakened them. From the 3-years' trial the conclusion is drawn that in 

 favorable seasons the practice increases the returns without being harmful or inter- 

 fering with the longevity of the vine; but where the grower is dependent upon 

 the rains in a dry district, it is both dangerous and undesirable. 



The handbook of horticulture and viticulture of "Western Australia, A. 

 Despeissis {Perth: W. A. Watso)i, God. Printer, 1903, 2. ed., pp. 620, ph. S, figs 299).— 

 This is a very comprehensive guide to the propagation, culture, and marketing of all 

 the usual fruits, and, to a more limited extent, vegetables grown in Western 

 Australia. 



A laboratory manual in systematic pomology, U. P. Hedrick {Mich. Agr. 

 Col., pp. 91). — This manual represents "an effort to place before the students of 

 pomology in the Michigan Agricultural College a means by which an intimate and 

 accurate knowledge of pomology may be acquired."
