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. 1st, 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. 

 Tt 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 & Co., Engineers. The foundations are indurated sand and the abutments dis- 

 integrated sandstone. Dam is 60' high 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 9' of flood and operated 

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

 pleted December 20th, three months ahead of time and well within estimated cost. 



CANNON FALLS DAM 



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

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

 concrete extended by earth embankments. Contract signed In February, first concrete placed June 15th. 

 work compled December 15th. This record was made notwithstanding extraordinary difficulties disclosed 

 in the foundation after work was begun. 



CEDAR FALLS DAM 



For the Cliippewa Valley Railway Light & Power Co. on Red Cedar River near Menomonie, Wis. 

 Dam is 5fl' high, 540' long, with a four unit power house. Contract signed In February,nnd 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. 



Tt 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 ffi' 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 alreadv 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 unit 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 1st. The conditions of water control are 

 particularly embarrassing. 

 BASSANO DAM 



fing ID 01 clay, and this carried on sand ol an unknown dep 

 carried on through the winter notwithstanding the high latitude. 



PORTO RICO DAM 



rUKTU K1CO DAM 



Dam 125' high and 440' long in a canon of the Catano 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 Compaliy, 

 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 your congratulations and extend to you 

 our New Year Greetings,
