pavement which they are now coll structinS in lola with a concrete base It has always seemed to Inc that either a cement or brick base would be very much better than the earth and I certainly believe that il will prove to be a good pave ment.
 The paving machines have been looked into and examined by eli gineers and paving contractors from all over the country and it seems to be very well thought of. I do not believe your people will be mak- ing any mistake if they use this kind of paving.
 "If there is any further information that I can give you. please let me know.

 In a letter from MT T. Fl. Eowlus. president of the Allen County State Bank. he states. after expressing his objection to the pavement laid On a dirt base. as follows:
 There is now a lot of it being put down on concrete base and that ought to do better. One small piece of this kind has been in use
  well but that is all there is to judge by as near as I can recall. II really looks like this would be all right judging from present appearances but several years wear will be re- quired to give it thorough and reliable test
 "To sum it all up I would not consider il on a dirt base at all but if used on a concrete base IF promises very good results although it has hardly been in use long enough to speak connclusively.
 It makes a very pretty pavement and if if holds up I see no reason why 1t should not come into general use
 Yours very truly. TIIOS. r. BOWJ-I.S'' Mir. " s. Gearhart writing Us uu- der recent date as to the National pavement. states as follows: Dear Sir:
 Yours of the 14th ult. concerning the National pavement which has been experimcnted with at lola. Kansas. has been received. T have inspected the paving these people have built several times and | it seemed to be showing up fairly ! well However. I think it is all on ! resident streets where the traffic is | light. It is my judgment that be- | fore the pavement will be adopted at ! all generally. they will have to de- i wise some means b. which it can | be built al a lower first cost. Other ' pavemen;s which have been thor ! oughly tested can be built for about i tho same price this company feels | that they must ask for their oiled earth
 { None Of this pavement ever hay ] ing been laid in Phoenix. it is 2 ! little difficult SO make a close esti-
 mate as to what it would cost here. but it probably can be laid on a
 inch concrete base for about sI.56
 per scuare yard. and if laid on a
 natural earth base. five inches or this mixture could be laid at from : 70 to 75 cents per square yard. Ii iS ! possible that under local climate and ! soil conditions. this pavement could 1 be laid in the residential districts [ which are practically free from ! heavy traffic. on an earth base with 1 safety. Tn such case great care ! however. would have to be given 10 ! the even compression of thc earth ! base. and the districts paved assured | of good drainage. Tn view cr the | compa ratiVely short time that this ! pavement has been in use. no ver- ! valuable figures are available as to ' the cost of maintenance. but oUire. ! Jo the composition of this pavement | the maintenance cost should be com ] par2tively low.
