on which has been begnn. A nnniber (if other experimental ])lantations are reported 

 upon and tables given showing the financial returns from the different regions. 

 During the year covered by this report the total income from the forests amounted 

 to 7,706,324 rupees, equivalent to more than $2,500,000, a decrease of about $100,000 

 from the revenue of the previous year. This decrease is said to be attril)uted to a 

 p»-olonged dry season, which prevented the marketing of a large amount of timber. 



Report on forest administration in the Punjab for 1900-1901, C. F. Elliott 

 {lipt. Forest Admin. Punjab, 1900-1901, pp. 80) . — The forest area of the Punjab, under 

 the administration of the authorities, amounts to 0,408,272 acres, which is classified 

 as reserve, protected, and unclassified. The increase during the year covered by the 

 report amounted to 353,320 acres. During the year covered by the report the cul- 

 tural operations and exploitation were seriously hindered by the prevailing drought. 

 The nund>er of forest fires decreased from 227 to 140, and the area Imrned over 

 diminished in nearly equal proportion. The net income received from the various 

 forest products was 36 per cent of the gross receipts. Detailed reports are given 

 of the natural results and operations in the different districts. 



Report of forest administration in tlie Hyderabad assigned districts, 1900- 

 1901, C. Bagshawe (R]>I. Forest Admin. Ilnderrihad, 1900-1901, pp. 41). — During the 

 year covered by this report 223 s(]uare miles were removed from the forest area of 

 the Hyderabad district, wiiich at present consists of 3,953 square miles. Owing to 

 the drought the income from grazing was greatly reduced and the net receipts of the 

 connnissioner <jf forests were abotit 50 per cent less than the ])revious year. The 

 working plants of the different divisions are described and di.scussed in detail. The 

 area of state forests in different districts is shown in tabular form, as well as the pro- 

 duction of tiMd)er, fuel, and other forest products. 



City forestry, L. A. (tOodman {Missonrl Stole lid. A(jr. Rpt. 1902, pyp. 439-448).— 

 The desirability of tree iilanting in cities is pointed out and suggestions given for the 

 growing, planting, and handling of trees, as well as for their protection. 



Winter aspect of the "woods, Charlotte M. King (Proc. Iowa Park and Forestry 

 Asmc, 1 {1901), pp. 71-74, fig. 1). — Brief notes are given on the wdnter condition of 

 a number of the more conuuon forest trees. 



The cork oak, J. H. Maiden {Agr. Gaz. New South Wales, IS {1902), No. .2, pp. 

 187-190, pis. 2). — A description is given of the growth of the cork oak ( (^iterrns snber) 

 in New South Wales. .Several specimens are described, whicli are said to have made 

 a satisfactory growth, and the tree is believed to be adapted to a nundier of localities 

 throughout the country. Young trees are offered for planting in different regions to 

 test the suitability of different regions for the growing of this important tree. Notes 

 are given relative to the growing of the cork oak in Queensland, California, and 

 elsewdiere. 



The comparative temperature of birch, fir, and pine, V. T. Luguinine {Izv. 

 MoscoivSeld-. Klio:. hist. {Ann. Inst. Agron. Mosrov.'], 7 {1901), No. 2, pp. 71-84).— Two 

 series of experiuients were carried on l)y the author between Ajiril, 1889, and Decem- 

 ber, 1892, in which the internal temperature of birch, fir, and pine was investigated. 

 The first series of experiments was conducted on birch and fir which grew on clay 

 soil, the trees having attained a diameter of 30 cm. The birch and pine in the sec- 

 ond experiment grew on sandy soil and were all about the same average size. The 

 thermometers used were bent at right angles, the shorter limb carrying the mercury 

 bulb inserted into the interior of the trunk on the north side, the longer limb remain- 

 ing parallel to the trunk. Readings were taken in the first series three times a day 

 during the vegetative period of the trees and once a day during the remainder of the 

 year. In the second series the readings were made daily at 1 p. m. The results of 

 investigations are shown in curves wliich indicate the differences in temperature 

 between the birch and fir on the one hand and 'the bircli and pine on the other. 

 The curves show that during the summer months the temperature fluctuated with
