XII. Read and translate the following extract with the help of a dictionary.

Transportation of pipes

To build a pipe line lengths of a chosen diameter are to be delivered from the place they were manufactured. They have to be unloaded at nearby railway station and transported along the right-of-way in motor trucks, wagons or lorries. Care should be taken to unload just the proper number of joints per mile. In this case there will be neither a shortage of pipe nor a surplus when the joints are coupled together. Then the joints are strung, or laid on the ground, end to end so that the laying crew will not be delayed in their work.
