pointed on May 25, and the remaining two a little later. The

The report of the committee, which was handed in on January 

 9, 1864, more than seven months after its appointment, occupies 

 fifteen pages, and treats of the different aspects of the publication 

 of the charts and sailing directions considerably in detail. It

On the practical side, the opinion of the committee was that 

 while the data presented were valuable, the form in which they 

 appeared was such as to confuse rather than aid and inform the 

 navigator. 



The committee sums up as follows :

 execution that is faulty. It was fitting that the laborious analysis of ships' records
