localities and horizons, hut usually in \cvy small f ragmen ts, consisting 

 of the tips of the pinnules of ferns, cycads, ete. On the South I'ork of 

 Elder Creek, from li to 2 miles above Lowry, at and below tlu^ dam, 

 plants also occur in nuich the same condition as at the last-mentioned 

 localities. Fai'ther up the South P'ork, l)elow Coopers, 5 miles south- 

 west of ]>owrys, near the gorge whei-e IIh> South fork cuts tlu'ough a 

 heavy bed of conglomerate, we found a t)ed that yielded fei-ns, cfcadaceous 

 leaves, etc., and made a considerable collection. 



The most southern point visited was Wilcox's ranch, (5 miles soutli 

 of Lowry, and over the divide between I'Hder Creek and Thome ('reek, 

 on the road to Paskenta. Mr. Storrs had found one specimen here on a 

 fomier occasion, l)ut we were unable to find any more at the original 

 locality. At another place, half a mile east of Wilcox's, we found some 

 very imperfect fragments. Just on the crest of the divide, about midway 

 between Lowry and Wilcox's, a bed was discovered l)v the roadside 

 containing delic^ate fern impressions and detached cycadaceous leaflets. 

 They occiu' in a rather fine sandstone shale, slightly concretionary, and 

 were found on both sides of the road, but chiefly on the east side, at 

 two horizons 80 feet apart. A large number of specimens were obtained. 



A single dicotyledonous leaf had been collected by Doctor Stanton 

 in 1893 from a locality 2^ miles below, or to the east of Lowry, on Eldei' 

 Creek, and Mr. Storrs and 1 tried to find the spot, but prol^ably failed. 

 At least we found no fossil plants in that general region. Half a mile 

 above, however, on the left bank of Elder Creek, a few fragments were 

 broken out of a coarse sandstone ledge, one of which was a small fern, 

 and the rest seemed to be pine needles. A much better locality, and one 

 that had not been previously discovered, was at the eroded end of a low 

 ridge run-ning north from Elder Creek, only half a mile below Lowry. 

 In a light-brown sandstone ledgie at this point there occur well-preserved 

 dicotyledonous leaves and some other vegetable impressions, of which we 

 made a considerable collection. As in the case of the dicotyledons 

 found at the mouth of Hulen Creek, these leaves are reserved for a 

 future paper. 



The last-named locality belongs to the upper Horsetown beds 

 according to the sections that have been made, but the specimen collected 

 by Doctor Stanton 2 miles below comes well up in the Chico. It was on
