correlates as the Loveland. If the correlations of the gumbo alone were 
all that is involved it would be advisable to adopt the term Loveland 
for these gumbo deposits of south central Iowa. There is, however, a 
serious objection to the adoption of this term.. The term Loveland as 
originally defined by Professor Shimek applies to a definite gumbo-like 
deposit and that only. In south central Iowa the gumbo may in places 
be traced horizontally into stratified sand ; in places it is found to con- 
tain a few pebbles, and in places to be free from pebbles;. The term 
Buchanan gravels was proposed by Calvin as the name for the gravels 
and the gravels only as found on the Kansan drift in Buchanan county. 
To adopt either of these terms would necessitate a change in the use 
of the term as originally defined. The writer therefore suggests the 
term Dallas for those deposits of whatever nature, partly gravel, partly 
sand, partly gumbo either without pebbles or with a few pebbles, formed 
in the closing stages of the Kansan ice age as the Kansan ice melted 
leaving a surface deposit over the Kansan drift in the Kansan upland 
and down along valleys which in places had by that time been eroded 
into the Kansan drift. The name is suggested by the town of Dallas 
in Marion county (Iowa) near which a considerable variation may 
be seen in the gumbo and associated deposits. A mile north of Dallas 
(Ne. Vt of the Ne. % of section 2) these Dallas deposits are pebble free 
beneath the soil, pebble bearing from eight to sixteen feet below the 
surface, and resting on a distinct sandy Kansan drift with its char- 
acteristic pebbles and bowlders, which in turn rests upon the Des Moines 
shales. A similar relation is observed in each of several exposures 
toward the south as far as the Lucas county line. To the north an 
excellent exposure may be found near the Fairview school house (T. 
75 N., R. 21 W., Sec. 3, Se. % of the Sw. VL)> where gumbo is seen not 
distinctly separated from Kansan drift. It may also be seen in the 
long cut east of Sandyville as previously described. In Lucas county 
it is especially noticeable in sections 23 and 34 of English township, 
10 of Lincoln township, at Chariton at the crossing of the C., B and Q. 
railroad, and in sections 8, 16 and center of 21 of Benton township. 
In Wayne county the relation may be seen in sections 5, 18, 30 and 31 
of Union township, in the northwest part of Corydon township, in sec- 
tion 24 of Benton township, and section 2 of Warren township. (From 
Allerton to Lineville the railroad follows a divide.) 
The name Dallas for these deposits is suggested to meet the need for 
a name that has not as yet been fully supplied. Should later a more 
acceptable term be found, or even an earlier term be given a new mean-
