quiries throughout the length and breadth of the timber-producing 

 regions of the States. Starting from New York, he proceeded 

 through the timber districts in the north of that State and Ohio, 

 crossing Lake Erie from Buffalo to Detroit, in the celebrated timber- 

 producing State of Michigan, visiting the great timber depots at Bay 

 City, Saginaw, and Grand Eapids ; then across Lake Michigan to 

 Milwaukie, and on to Chicago in the north of the State of Illinois, 

 famous for its extensive timber and grain depots, and its marvellous 

 growth of population and rapid resuscitation from the effects of big 

 fires. From thence Dr. Hough proceeded north, again visiting Free- 

 port and INIadison, and right on through the timber districts of 

 Northern Wisconsin to the shores of Lake Superior at Duluth ; 

 turning south' at this point, and investigating the famous timber- 

 producing regions in the valley of the Upper Mississippi, in the 

 neighbourhood of St. Paul, IVIinnesota. He next proceeded southward 

 through Minnesota and Iowa to Omaha, and then westward along tlie 

 timber tracts of the Eiver Platte, in the State of Nebraska ; on 

 through Wyoming to the "City of the Saints" in Utah, and up tO' 

 the top of the Wahsatch Mountains, an elevation of some 12,000 feet 

 above the level of the sea. The Mormons of Salt Lake City seem to 

 have shown the traveller every courtesy, and by the assistance and 

 suggestions of Brigham Young he was enabled to visit and inspect 

 the timber region of the Big Cotton Wind Canyon, from whence they 

 derive their chief supply of timber. Eeturning east, he visited the 

 Eocky Mountain regions in the State of Colorado, inspecting the various 

 famed timber districts, and then onwards through the State of 

 Kansas to Kansas City, and northwards from there along the Missis- 

 sippi Valley to Omaha. From there he journeyed homewards- 

 through Iowa, Illinois, Indiana, Ohio, and Pennsylvania to New 

 York, having traversed a distance of something like 8,200 miles, in 

 pursuit of the' valuable statistics and general information upon the 

 subject which he incorporated in the report now laid before Con- 

 gress, 



To help him in attaining his object, Dr. Hough also entered into aa 

 extensive correspondence with the officers connected with the forest 

 management and forest schools which abound in Europe, and from 

 whose matured experience and opinions upon such matters of vital 

 interest he has gleaned a vast amount of valuable information, 

 which he has made excellent use of in his report. The report is 

 accompanied with numerous illustrations of various kinds, beautifully 

 engraved by the " relief-heliotype " process, a novel feature of great 

 interest, and especially so when applied, as it is here, to the graphic 

 method of presenting statistical facts and scientific comparisons when, 

 numerically expressed. Besides the chapters which deal witli statis-
