by hard labor, listening to the notes 

 of the birds and seeing their brilliant 

 forms flit from tree to tree. The lit- 

 tle grove seemed to be fairly alive with 

 birds of several different kinds: Red- 

 headed Woodpeckers, Scarlet Tana- 

 gars. Flycatchers, Warblers, Creepers, 

 and other birds too numerous to men- 

 tion. The Blue Jays made the air 

 "squeak" with their note, which re- 

 sembles nothing so much as the squeak- 

 ing of a rusty hinge. 



From this point we walked (part of 

 the way, wadedj to the big ditch which 

 connects the Calumet River with Lake 

 Calumet. The north side of the ditch 

 was banked up high with debris dredg- 

 ed from the canal, and on this slope 

 the dead shells of mollusks are very 

 plentiful. We picked up a large 

 number of the following species; 

 Anondonta footiaiia, Unio liitcolus, 

 U. pustulosiis, U. gibbosus, LinuuBa 

 reficxa, L. stagualis, Planorbis trivol- 

 vis, P. campanulatiis, Vivipara con- 

 tcctoidcs,- Canipcloma decision, C. sub- 

 solidum, and Splnvrinni striatinuni. 



From this ditch we walked three 

 miles to Wolf Lake. This locality is 

 a very good one. The shores are 

 sloping, in some places sandy and at 

 others muddy, thus affording a good 

 habitat for a variety of forms of mol- 

 lusks. On the muddy bottoms we 

 found Vii'apara contrctoidcs in vast 

 numbers, and a few good specimens of 

 Canipcloma dccisuin, Unio luteolus 

 and U7iio gibbosus. On the sandy 

 bottoms Plenrocera subiilarc was found 

 by thousands. The shores of the lake 

 are wooded here and there and after a 

 rain many species of pulmonate mol- 

 lusks may be found about the dead 

 stumps and fallen trees. As it was 

 getting late, we were not able to ex- 

 plore these groves, but were content 

 to return with what we had already 

 obtained. These were, to sum up: 

 two snakes, two field mice, and about 

 200 living and a like number of dead 



mollusks of thirty species. Thus end- 

 ed our day's collecting.

A Pre-Historic Tomb- 

 About four miles west of Barnesville, 

 O. , is a ridge, known as the "High 

 Ridge," so called from its great height 

 over the surrounding country. A 

 burial place is situated at the very 

 verge of the south end of the ridge, 

 and to the northward for over 300 

 yards, is a moraine of small limestone, 

 the top being almost as level as a 

 floor. This leveling has evidently been 

 done by human hands. 



In building this tomb, the ground 

 seems to have been excavated to the 

 depth of three feet, the cavity being 

 ten feet east and west, and fifteen feet 

 north and south. Around this entire 

 hollow space, was a wall fully three 

 feet in height, built of small limestone. 

 At the south side of this was found the 

 remains of a tremendous human being 

 of long ago. The body had been 

 placed directly east and west, with the 

 head to the east. A large, fiat stone, 

 of peculiar shape, had been placed just 

 back of the head. 



The distance from where the heel 

 bones (Calcarreum), were lying, to the 

 point where the top of the skull was 

 found, was eight feet three inches. In 

 examining the fragments of the bones, 

 one is fully convinced of the great 

 stature of the person. There was a 

 large piece of the skull well preserved, 

 and about two-thirds of the jaw bone 

 was in good state preservation with 

 four back teeth firmly set in their sock- 

 ets. This bone is half as long again 

 as that of the ordinary person. The 

 crowns of the teeth are worn fiat, but 

 arc well kept. The wear of the teeth, 

 the porosity of the bones, and the ob- 

 literation of the sutures of the skull, 

 show that the subject was well up in 

 years. From the shape of the crania, 

 high forehead, large teeth, and long
