    Thanks Henry for the lead.
    
    I have doe a little search on the net and there appears to be another book
    called Avigation written by Harvey H. Holand and published in the very same
    year - 1931 by McGraw-Hill. Competition at its best! Any knowledge of which
    one is better? Price wise there is no ubtantial difference.
