1905-1910-1911 

 A Retrospect A Forecast 



It is with no small satisfaction that we contrast our condition at the close of 1910 with our expecta- 

 tions in 1905. At that time after two years of petty beginnings we were still a small organization occupying 

 restricted quarters and scarcely foreseeing the possibilities in our own selected field. 



Beginning with a single room we steadily increased at our old location, 170 Federal St., until after 

 occupying a suite of seven rooms there were no more available. We are now in our new quarters at 8S 

 Pearl St., occupying the entire fifth floor of a new building. Our floor space aggregates 6,000 square 

 feet, and being lit on four sides it has been possible for us to lay out an engineering office which for 

 convenience and adaptability not only fits our needs precisely, but is perhaps as excellent an example of 

 an engineering office considered as a working tool as can be found in the country. 



The Company is officered by five experienced men trained as specialists in hydraulic work and with 

 their efforts supplemented by a staff of advisers both in the office and in the field. Our operations at this 

 moment cover all sections of North America, from Alberta on the north, Newfoundland on the east, Porto 

 Rico on the south to Oregon on the west. It is our belief that no such efficient organization from head 

 to foot has ever been got together in a similar line of work. We are today prepared to undertake engineer- 

 ing and construction of any description associated with hydraulics and to execute it in record time and 

 at record cost. Notwithstanding the year 1910 has been with us a record year, the work now assured to 

 us makes it certain that the volume of our business for 1911 will be increased many fold. 



AH the above can be best illustrated by a brief review of the work accomplished during the past year. 



BISHOP'S FALLS DAM 



A structure of magnitude in connection with a pulp mill on the Exploits River, Newfoundland, for 

 the A. E. Reed Co. of London, Ltd. Dam is 51' high and 720' long, built under the supervision of George 

 F. Hardy, Engineer, to whom, by the way, we are indebted for our first large dam in 1904. Work was 

 begun in April and completed Nov. 1l, several months in advance of the anticipated time and well within 

 estimate of cost. 



ATHENS DAM 



For the James White Power Co. on the Oconee River near Athens, Ga. Now nearly completed although 

 the time of construction has been considerably prolonged owing to great difficulties with the foundations. 

 It is 52' high and 820' long, containing a four unit power house. Work was begun in February. 



RAPIDAN DAM 



A very important structure on Blue Earth River near Rapidan, Minn., built for the Consumers Power 

 Co. under H. M. Byllesby S: Co., Engineers. The foundations are indurated sand and the abutments dis- 

 integrated sandstone. Dam is CO' hich and 450' long, containing a three unit power house. A highway 

 bridge is carried across 72' above tail water. It has a movable crest controlling 0' of flood and operated 

 from the highway. Contract was signed early in February, first concrete laid June 15th and work com- 

 pleted December 2Oth, three months ahead of time nt:d well within estimated cost. 



CANNON FALLS DAM 



On Cannon River near Cannon Falls, Minn., also built for Consumers Power Co. under th_' same 

 engineers as above. The concrete portion is 1,023' long and 62' high, containing a four unit power house, 

 concrete extended by earth embankment's. Contract signed In February, first concrete placed June 15th, 

 work compled December 1 5th. This record was mnde notwithstanding extraordinary difficulties disclosed 

 in the foundation after work was lirpun 



CEDAR FALLS DAM 



For the Chippewa Valley Railway Light & Power Co. on Red Cedar River near .Mur.omoiiiL-, Wis. 

 Dam is 50' high, 540' long, with a four unit power house. Contract signed in February, mil work com- 

 pleted November 1st, and the current from the generators was sold to the users on December 1st. The 



work was executed well within its estimated cost. 



It is probable that these three dams taken collectively mark a record never before attained in hydraulic 

 construction of magnitude both as to time and relation to estimated cost. 



ESTACADA DAM 



Dam 86' high and 865' long, for the Portland Railway Light & Power Co. on the Clackamas River 

 near Estacada, Ore. Work is now in progress under Sellers & Rippey of Philadelphia, Engineers, being 

 the third dam that we have already build for these engineers and the capital which they represent, and 

 is executed by the Puget Sound Bridge and Dredging Co., our* Associated Engineers. 



DANVILLE DAM 



A small reservoir dam only 14' high and 280' long for the city of Danville, Ky. It is the second 

 dam that we have built for this city and the reason why we do not print the letter received from the city 

 official is because of the strain put upon our modesty. 



BEDFORD DAM 



A small dam 20' high and 500' long, including a five ur.it power house, on the White River, for Bed- 

 ford Power Co., Bedford, Ind. 



ALBERTON DAM 



On Patapsco River near Alberton, Md., for James S. Gary & Son, Baltimore. The work involved 

 the tearing out of the old wooden dam and replacing same with a reinforced concrete structure 30' high 

 and 285' long on very difficult foundations, and on condition that water be so controlled that mill opera- 

 lions be not suspended. Work started late in summer and having been now successfully completed the 

 construction force has been moved to the 



OELLA DAM 



This is the third dam built by us on the Patapsco River. Dam 26' high, 200' long, for W. J. Dickey 

 & Sons, Inc., Baltimore. Work has just been commenced and will be carried on through the winter. 



SOMERSET DAM 



A small dam 20' high and 200' long on the Apple River; this also for the Consumers Power Co., 

 under H. M. Byllesby & Co., Engineers. The work includes flumes, power house and general over-haul- 

 ing. Started on September 1st, and will be finished February Isf. The conditions of water control are 

 particularly embarrassing. 



BASSANO DAM 



This is a part of the large irrigation development now being carried out by the Canadian Pacific Rail- 

 road. On the Oxbow bend of the Bow River near Bassano, Alberta. In the engineering difficulties pre- 

 sented this is perhaps the most important work we have ever undertaken and in many respects the most 

 difficult piece of hydraulic work ever attempted by any one. Dam 51' high, 720' long, with 11' of flood 

 control on the crest, designed to pass a maximum flood of 100.000 cu. ft. per second. The difficulty lies 

 in the foundations which are without trace of rock in any form but consist of 3' of gravel over- 

 lying 15' of clay, and this carried on sand of an unknown depth. Work now in progress and will be 

 carried on through the winter notwithstanding the high latitude. 



PORTO RICO DAM 



Dam 125' high and 440' long in a canon of the C'ntano River near San Juan, for the Porto Rico 

 Light & Power Co. 



This year therefore rounds out a record of 60 dams built since the organization of the Company, 

 many of them being structures of the first magnitude and importance. We are therefore quite in the 

 mood to wish you the Compliments of the Season, ask of you yonr congratulations and extend to you 

 our New Year Greetings.
