This was made possible by consent of Colonel Roessler, Corps of Engineers, in charge of that work, who would not require the maximum delivery of stone until about the first of July. The first stone under this purchase was delivered on June 2, 1908, when a barge of about 1,500 tons arrived. Meantime the contractor is developing two quarries, one at Oakville and one at McCormick, Wash., along the line of the Northern Pacific Railway, and has not progressed far enough at this time for it to be made certain that stone from these sources will be acceptable. On May 20 the hydraulic pile driver was removed to the ocean end of the trestle and the work of advancing the trestle started. During the forty days this has been in operation the trestle has been advanced 1,568 feet, the end now being 2,624 feet from the ocean high-water line. The foundation mattresses have been laid and securely weighted with stone for a distance of 2,176 feet. The enrockment has been raised to and above midtide for a distance of 1,700 feet. The daily average advance of the trestle has been 45 feet. This, it is expected, will be increased after the workmen become more familiar with their duties, the organization at this time being new. The daily average advance of the foundation work has been 48 feet and is sufficient to admit of rock delivery to the full maximum rate provided for under the contract. At the close of the year material had been received in following quantities: Stone from Columbia River, open-market purchase, 2,866.158 tons, at $1.55 Stone under formal contract, 3,384 tons, at $1.55. 2,950 grillage poles, at 27 cents each--- 601 cords of brush fascines, at $2.50 per cord_ 868 cords of brush fascines, at $3 per cord_ 8,180 linear feet of piles, at 13 cents per linear foot.... $4, 442. 54 5, 245. 20 796.50 1, 502. 50 2, 604.00 1,063. 40 It is expected that the trestle will have advanced approximately 6,000 feet before the suspension of operations will be necessary this winter, and that throughout this whole length a foundation of brush fascines will be laid, having a width of 30 feet and a thickness of about 3 feet, and that the whole will be securely weighted with stone. That a portion of this length will have the enrockment carried up to the midtide height, thereby completing the work in accordance with the plan for that distance. A channel known locally as Seal Channel separates the north headline from the north spit and soundings taken along the proposed site of the jetty give a a maximum depth of 18 feet at mean lower low tide; the width of this channel is about 1,400 feet. In advance of this channel the north spit shows bare for a distance of about 800 feet to the low-water line of the bay lying between the north spit and the bar. It is expected that the jetty construction will reach the north spit by the 1st of August; that the foundation work will closely follow the trestle construction, and that the enrockment work will be carried some distance landward from the foundation work, thus lessening the scour around the end of the trestle as it advances, due to a cutting off of the tides where the enrockment work follows closely the trestle and foundation construction. The work is too young yet to note any improvement just at this time.

IMPROVEMENT OF GRAYS HARBOR, INNER PORTION, BETWEEN ABERDEEN AND THE ENTRANCE TO SAID HARBOR, AND CHEHALIS RIVER, WASHINGTON. The following extract from the report of Mr. J. M. Clapp, assistant engineer, describes the operations for the year: In September, October, and November, 1907, a thorough survey of that part of the river between Aberdeen and Grays Harbor City was made. Cross-sections were made at every 50 feet of the channel its entire distance of 5 miles. From these new data a map was prepared and the channel to be dredged accurately located, advantage being taken to include the deeper portions within the channel's limits. Bids were called for on July 12, 1907, for doing the work under the new appropriation, which contemplated the removal of 1,250,000 cubic yards, if the price were within the estimate. The lowest bid was that of the North American Dredging Company, the price being 15 cents per cubic yard, place measurement, and on August 8, 1907, a contract was entered into with this company to do the work. Upon computing the quantities for the excavation of this channel it was found that the funds would not admit of a channel 200 feet wide on the bottom, side slopes of 1 on 2, and to a depth of 18 feet being dredged at the price bid, and that considerable shoaling had taken place. An increased yardage was also included by a specification requiring the contractor to be allowed payment for 1 foot over depth. A modification in the channel's dimensions was therefore necessary. The work to be done was located at two points-one above the mouth of the Hoquiam River known as Cow Point bar, and the other below the Hoquiam River known as the lower shoal. The final adjustment of the channel dimensions admitted of a continuous channel being excavated the full length of the shoals. At Cow Point bar it was to be 175 feet wide on the bottom, 17 feet deep at mean lower low water, with side slopes 1 on 2; and 160 feet wide on the bottom with side slopes 1 on 2 and to a depth of 17 feet at mean lower low water through the lower shoal; the contractor, in both cases, to be paid for an overdepth of 1 foot should it be carried below 17 feet, this to be determined from surveys of the dredged channel. |
