In 1907, this arrangement was modified by an extension of the leases of the railways from 1956 to 1973, by a reduction in the number of annual payments from 33 to 30, and by a further agreement on the part of the Peruvian Corporation to construct certain railroad extensions to Cuzco and to Huancayo. The bonds of this corporation were largely held by English, French, and Dutch subjects. Consequently, the diplomatic representatives of these countries in Peru sought proper interest in the welfare of their nationals, the bondholders.
