tamed a small lake surrounded by trees and proved a favorite 

 haunt of birds. The meadow was variegated with flowers, helle- 

 bore, painted cup, and larkspur. The cattlemen say that larkspur 

 and wild parsley are fatal to cattle and they never keep their stock 

 more than one night in this region. They claim horses are not 

 affected. Flying squirrels were abundant and easily trapped in 

 the higher groves of red fir, and we also secured several marten 

 here. Mr. Baker shot a magnificent buck on a high ridge to the 

 south. Zapus lived among the alders along the stream. The Lincoln 

 sparrow was nesting here in a clump of hellebore. The zone may be 

 therefore considered Canadian. 



On August 2 we made a forced march back to Callahan, over 

 the Rush Creek Divide, around the heads of Taylor Creek and one 

 of the branches of Coffee Creek, down into the East Fork of the 

 Salmon River, up again until we struck the Scott River watershed, 

 and thence down into Callahan. 



Kangaroo Creek, a tributary of Scott River, then became our 

 base of operations. Our camp here was situated at some deserted 

 mining cabins about eight miles northeast from Callahan and 

 several hundred feet higher, at an altitude of 3300 feet. We 

 were disappointed to find that hydraulic mining had been carried 

 on in the creek, thus spoiling all the natural aspect of the place. 

 Also there was almost no water except from a small spring near 

 the buildings, so that any hope of finding many small mammals was 

 vain. The side-hills were dry and unattractive, and birds conse- 

 quently scarce. 



The thing of chief interest about the place was the mixture of 

 zones, for we here found round-tailed wood rats and bushy-tailed 

 ones inhabiting the same cabins. Also there were golden-mantled 

 ground squirrels, which, with the bushy-tailed wood rats, must 

 have been at the lowest line of their distribution. The place being 

 shut in, as it is, in the canon, is probably somewhat colder in winter 

 than at Callahan, although there is so little difference in altitude 

 and general conditions ; this, combined with heavier timber, may 

 account for the presence of the two high-zone mammals named. 

 The tree stand is chiefly yellow pine. The locality may be consid- 

 ered prevailingly Transition. 



The collecting at Kangaroo Creek was so disappointing that 

 after two days' work we were glad to start for Bear Creek, one 

 of the northern tributaries of the Trinity River, and at the base of
