Buenos Aires to Tokyo #416.
Strictly secret; C. O. R.
When Minister Yamagata* was in Panama he was asked by the Italian Minister there to deliver some maps and charts of the Panama Canal Zone for him, which he did. Since then, we had Usui go to Chile to take charge of those maps and upon their arrival here they were delivered to the Italian Ambassador. At the same time, we requested that we be given copies of them.
Recently, these copies were delivered to us. (At the time of this delivery, Assistant Attache Kameda and Usua were present to ascertain that they were exact copies of the originals). And we entrusted them to our Navy's courier Tatuma who is returning home on the Buenos Aires Maru.
The Italian Ambassador here requests that upon the arrival of these papers in Tokyo, we notify the Italian Government to that effect through (our Embassy in Rome?)
Minister Yamagata has already advised Chief of Bureau Terasaki regarding this matter. The Navy has also sent a report.
