SUPPLEMENTARY REPORT OF EXPERIMENTS MADE AT GARDEN CITY, 
DODGE CITY, BUCKLIN, AND FORD, KANS., 1908. 
SAND clay. 
The original report of these experiments was published in Circular 
No. 90, and reports of annual inspections are given in Circulars Xos. 
92. 94, 98, and 99. The following are reports of inspections made 
in 1913. 
Experiment at Gaedex City. 
The Santa Fe Road at Garden City. Kans., 12 by 765 feet, was 
inspected on December 19, and found to be in poor condition. The 
recent rains have had a damaging effect upon the gypsum clay 
surfacing, and have softened it into a muck-like condition varying 
from 2 to 4 inches in depth. This is more noticeable at the north 
end where some new gypsum has been added without sand, but the 
mud is in evidence throughout the entire course. The road has re- 
cently been worked with a small 2-horse grader, and the material has 
been pushed to the center in such a way as to give a uniform slope 
and crown. The road is reported to have been in excellent condition 
all last summer and will be so again as soon as it is dried out. 
Experiment at Dodge City. 
The Alineola Road, improved by a clay and sand composition 14 
by 9,750 feet, was inspected on December 19. 1913. and found to be 
generally in good condition throughout the whole course, with one 
exception, where a chuck hole of minor importance was in evidence. 
The ditches were in good order, the cross section uniform, and the 
edges of surfacing not broken by the attacks of traffic. It has been 
well maintained by dragging done by a near-by farmer whenever 
necessary, but. owing to recent and continuous rains for two weeks, 
the surface of the roadway had softened to the extent of being 
deformed by traffic, showing slight hoof marks and incipient ruts. 
At. the extreme north end, for a distance of 75 feet, some new mate- 
rial has been added and left in an urifjuished condition. 
Experiment at Bucexix. 
The Spearville Road, at Bucklin, Kans.. was inspected on Decem- 
ber 20, 1913. and the clayed surfacing, which was 14 by 4.271 feet,
