The following, being a part of the code prescribed for use at Willows, will serve to indicate the nature of the whole scheme:— _Africa_, Perfectly clear throughout the whole eclipse. _Alaska_, Perfectly clear during totality. _Belgium_, Clear sky for the partial phases, but cloudy for totality. _Bolivia_, Entirely cloudy throughout the whole eclipse. _Brazil_, Observed all the contacts. _Bremen_, Observed three of the contacts. _Ceylon_, Made observations on the shadow-bands. _Chili_, Observed lines of the reversing layer visually. _China_, The Corona showed great detail. _Cork_, Obtained 40-50 negatives during totality. _Corsica_, Obtained 50-60 negatives during totality. _Crimea_, Obtained 60-70 negatives during totality. _Cuba_, Observed a comet. Upwards of twenty codes were prepared for the like number of stations, and the observers were to report their results at the earliest possible moment. On a rehearsal of the programme the thought occurred that the sending and reception of so many cypher messages in the ordinary course of business might lead to delays which would be productive of serious inconvenience, and that the success of the whole scheme could be only well assured if a special wire, in direct circuit from New York to the eclipse stations in turn, could be dedicated to the work. Thanks to the liberality of the Western Union Telegraph Company this privilege was secured, and a branch wire was led across from the Company’s New York office to the office of the _New York Herald_, which journal had undertaken to be responsible for the non-astronomical part of the business.
