CONSTRUCTION MATERIALS
Concrete and Steel in One Way or Another, Provid- ed for by All Competitors Plans Are Referred to Board of Engineers

The board of supervisors yesterday received from nine construction firms and will turn over to its special board of engineers appointed for that pur- pose, plans and estimates of cost of construction, or bids for construction, in accordance with plans submitted, of a bridge over Salt river at the Center street side.
 With the exception of one firm, Knipe & Davis of this city, the plans are all for concrete bridges reinforced with steel, none of them exceeding in length 25OO linear feet. The knipe & Davis plans call for a bridge 29O0 feet long. constructed of steel, reinforced with concfete. "Our plans,'' said MT. Davis last evening, -are guaranteed by the American Bridge company, the largest firm of the kind in the world
 It would be impossible for any per son, even an engineer, to do justice to any or all of the plans submitted in a hasty review of their merits Their greatest merits or their possible defects might be overlooked in such an examination. The supervisors recognized this fact in their appoint ment of a special board of engineers, who will meet and take up the con sideration of the plans in detail on September l3. This board consists of J. C. Mcclure of Tucson and Arthur l.. Sonderegger and F. l.. Quinton of Los Angeles, all recognized as gentle men of high standing in the engineer ing world. All that can be said of the plans at this time and said fairly is that from the standpoint of the lay man they all look good on paper A high degree of art as well as engineer ing skill is shown in some of them, the detail work being as carefully done as though they were to be Judged py hoard of art connoiseurs One of them shows a water color picture of the bridge as it would appear when i'm ished in accordance with the accom- panying plans submitted. and many, II not all. of them show similar pictures in line drawings.
 A considerable number of citizens were present when the plans were opened, as the question has become one of more than passing interest in the community. The firms submitting plans and their estimates, as far as they could be discovered from the ac- companying letters of transmission, are as follows:
 Frank Parker & Dunlap of East Lansing, Mich, s96,0O0; A. O. Gun ningham and A. E. Lindan of St Louls' S95. 900. or with a sidewalk also' slO4. .OOO: Charles Worthington of New York, S1OO.0OO.
 A. H. Koebig of Los Angeles sub mitted two definite propositions or estimated cos. of materials and labor, each with tentative propositions. Also they wired concerning another set of plans to be considered, which plans did not arrive until few minutes past o'clock yesterday. Neither these plans nor the preceding ones showed on the face of them to the casual op- server just what the total cost would be in using any one set of them, wlth- out an estimate, nor is It known whether consideration will be gwen the last set of plans received IL IS understood MT. Koebig's attorney says the cost of the bridge under his plans would be 95,OOO Mayberry & Parker of Los Angeles submitted plans ana estimate of S1OO,000. Howard NJ Jones of Nashville submitted plans and estl- mate of s93.O0O. w. H. Cowen and John F Blee of Los Angeles suD- mitted plars. E. H. Warner of Los Angeles submitted plans and estimate of s1O0,OOO. Knipe & Davis of Phoe- nix submitted plans and estimate or S91,OO0. As the public is now quite well aware, the local situation Is that the county has at its disposal SlOO,oco with which to build the bridge, one half by bond election and the other half bonus that has been guaranteed by the Bartlett Heard company.
