Mr. Am)K1{.s()\. Well, 1 have not done any traveling; in Californiu,

Mr. Anderson. Your next item is; 



For in vest ipat ions of the best method.'^ of road making, e8p«»eially by the uw of 

 local materials; for studyiiifj the types of incchaniia! plants and applian<M's ns«'d for 

 road Imildiiij,' and mainlenance; for studying methods of road repair and maintcnuQce 

 suited to the netnls of different localities; and for furnishing export ad\'i«-e on these

Mr. MacDonai.I). I'nder tliis item we have been makinj; a number 

 of studies of the use of local road materials, for exampl(>. in the 

 Southern States, the use of sand-clay roads. We have found in the 

 Southern States the need of a threat deal of pioneerin«j work, that is 

 the cleaning, j'rading, draining, putting in the subdrainage where 

 necessary and l)uilding the bridges and cidverls. This character of 

 work has recjuiied the available funds and has necessitated our using 

 local cheap nniterials for surfacing, such as the sanil clay and top 

 soil. We also have been cooperating witli the State of California, 

 and the Cohnnbia Steel Co., in the I'ittsbingh, Calif., tests. In that

 reinforced concrete sections. The trucks were operated over the
