Navigation on the Nile Its revenue fell short of expectations by £12,000 due to the shift of all trade to the railway, and because the livestock trade did not reach the expected level. Ports and Lighthouses Their revenue fell short of what was estimated, the main reason for this being the high cost of money in England and the blockade of the Red Sea. However, the reasons for the decline are temporary, and once they are removed, Port Sudan will undoubtedly return to increased importance. Roads and Wells 1598 new roads and 106 new wells were opened this year. Post and Telegraphs The revenue from this service fell short of expectations, but it still increased by 4 percent compared to 1911. Ordinary correspondence fell short by about 10 percent, but this shortfall is not significant and depends on the time taken for review. The number of telegrams increased by 6 percent, and this is reflected in the revenue. No new telegraph lines were added this year, and there are now 4,774 miles of lines and 98,964 miles of wire. The telephone continues to expand and grow, especially in the cities. Chapter Four On Agriculture and Irrigation Irrigation The Nile flood was the lowest recorded in many years. The construction of barrages, which are to be built on the White Nile near its confluence with the Blue Nile, will make Egypt safe from the dangers of fluctuations in years when the flood is below average.
