IN "On This Day" recently, you stated that in 1904 work on the Panama Canal started. This is wildly inaccurate. Work was started in 1879 by the French; the engineer was M Ferdinand de Lesseps, who had recently constructed the Suez Canal. The venture was ill-fated, beset with tremendous obstacles, and the death of a large proportion of the work force by disease. An Englishman (I forget his name) discovered that the malaria parasite was transmitted by the Anofolene mosquito in the early 1900s. The USA bought out the French and, using steam shovel technology developed in building the Manchester Ship Canal, completed the canal using locks. de Lesseps' plan was a sea level canal, which was not practicable.

The primary job of the USA was to eliminate the mosquito breeding ponds, so dramatically reducing sickness of the workers.
