The Company has been continuously engaged on these projects from that time to this day.\nThe first construction projects entered upon were the Boghra Diversion Dam on the Helmand River, a few miles above Grishk, and the Boghra Canal. The Canal had been started some years previously and had been partially excavated by hand labour methods. After MKA took over the contract, they brought in heavy equipment and tractors, \"Carryall\" scrapers power shovels and draglines of large capacity, etc., and the job proceeded on a production basis. By May of 1950, the first 40 miles of the canal had been dug and the necessary concrete structures built, including three long, large-diameter siphons and three shorter siphons crossing under major \"Mandas\". At one point in the canal, near Girishk, a power drop was provided, and the concrete structures for a hydro-electric power plant was built to provide for future power installation.\nIn April, 1950, the Government entered into a second con-tract with MKA for additional public works construction, and negotiated an agreement with the U. S. Export-Import Bank of Washington for a loan of 21 million dollars to finance the work. The new contract provided for the construction of (1) a dam on the Helmand near Kajaki, about 60 miles above Grishk, (2) a dam on the Arghandad river, below the village of Dahla","chars":1853,"image":"https://storage.googleapis.com/adl-page-images/adl0957/00064.jpg","first_page":1,"last_page":377,"title":"new guide to Afghanistan","permalink":"https://afghanpress.org/book/adl0957/64","canvas":"https://afghanpress.org/iiif/adl0957/canvas/64","source":"https://afghanistandl.nyu.edu/books/adl0957/","source_pdf":"https://afghanistandl.nyu.edu/pdf/adl0957_download.pdf","rights":{"image":{"statement":"Public domain.
