liNtI 10luS tue NpN uHuk IlOIH tIt north. heading well within the mountains to the north \ broad valley extends tor 10 to DO miles up from its mouth. Al the mouth of south fork the koyukuk makes a westerly bend and thence flows ill tortuous course across the low land for so miles to the Alatna river, where it turns to the south west. The source of the Alatna lies in the EndiCott mountains A portage trail connects the Alatna with the Kobuk waters. Below the mouth of the Alatna the kOyu- kuE flows southWesterly for 100 miles This portion of the valley is to2 miles wide, and the walls rise abruptly 10 an upland which stands between I, 800 to 2,ooo feet above the river.
 A few miles below the flats the kanuti river is tributary from ,he southeast Its source lies in a mountain mass 3 ,Ooo to 5000 feet ill height, which is drained in part by the Dall river.
 The Kanuti river is 200 miles long. and presents great physical diversity. 1t heads ill the same mountains whose northern slopes are drained by Fish creek and Jim river, but within a few miles of its source it enters q relatively flat basin, nine or ten miles long and half as wide, which contains anum- Der o' small lakes and ponds, al- though standing at an elevation of between |, 200 and HOO feet. This basin is q marsh covered with the usual tundra growth, At its lower end the river enters restricted valley, so steep walled in places as to deserve to be called a canyon and having maximum depth of 2,ooo feet. The gorgelike char aCter prevails for about 30 miles, and through this portion the river can scarcely be called navigable, since 1t is a succession of rapids, and the river channel throughout is obstruCted by bouldcrs of all sizes. Below this stretch the valley gradu- ally broadens.
 Within this lower basin the Ka- nuti river receives a large tributary from the south iii the direction of the sources of the TOzi and Melozi, and 25 miles above its mouth the river plunges into Q second canyon about 10 miles long and 500 feet in depth. This is the most beautiful section of the river; the stream is swift, but free from dangerous rap ids, and the bluffs of slate and sand stone rise sheer from the water to a height O! several hundred feet. Ten miles above the mouth it receives the waters of the Mentanontli.
 The hills which border this low CT section of the kanuti river and adjacent parts of the koyukuk are seldom more than I,5oo feet in height, are not excessively steep, and are we'll timbered,
 Near latitude 6 10 the koyu- kuk valley makes northwest bend. and 50 miles below swings to the southwest and the valley opens out. From this point to the Yukon the gradient is low and the river is tor tuous, with numerous channels.
 Below the Kanuti the Koyukuk receives a number of important tributaries. The Hogatza river interlocks its headwater drainage with southern tributaries of Kobuk, and the two drainage systems are connected by easy portage. The other tributaries of the lower Koyu- kuk flow from the west and are smaller than those described.
 In ordinary stages of water steam CTS ascend the Koyukuk 40 miles, the current averaging probably four miles an hour, and at high water steamers can be taken 100 miles farther upstream. The upper Roy ukuk and most of its tributaries are navigable for small boats only, and often not even for those, except in their lower courses.
 \ building will be erected on the summer garden behind Frac- tion bar. When completed 1t will be Occunied bN Nnahon. the
