THE thirtieth Universal Esperanto Congress will be held in London on July 30-August 6, under the high patronage of H.R.H. the Duke of Connaught. The total membership of the Congress is expected to be about 1,500, of whom some 1,300, representing twenty-five nationalities, had been enrolled at the beginning of June. The official proceedings will, as usual on these occasions, be carried on in the international language alone, no interpreters being employed either at the general meetings or at the sectional gatherings of specialists. Among the social features of the week will be two performances in Esperanto of "Eliza Comes to Stay" by members of the Neilson-Terry Guild of Dramatic Art, who have been learning the language for the purpose. It has been decided to hold next year's Congress at Bern, Switzerland.
