It is of interest, in connection with the French, to record the fact that the Swiss Federal Department of the Interior was much pre-occupied with the question of the preservation of walnut-trees. As a means to that end, grafting (_greffage_) as practised in France, but the method of which was unknown to the Swiss, was considered of great importance. Instructors were accordingly recruited from amongst the French Interned, and in January, 1917, as many as twenty men were engaged in imparting their knowledge to Swiss gardeners in different parts of the country. By December 31, 1916, out of a total of 28,081 Ps. of W., consisting of 1,879 British, 15,574 French, 1,893 Belgians, 8,504 Germans, and 231 Austrians, only 818 men of category 4 had found employment through the intermediary of the Labour Commissions, and even this limited number was distributed amongst as many as 741 different Swiss masters. As regards general and technical education, schools ("écoles nationales") were formed under the auspices of the officers in charge of the Interned. I am writing now only of the French, Belgians, and Germans. With the French and Belgians, attention was directed to _general_ education in elementary subjects, languages, literature, commerce and accounts, and to _technical_ instruction in agriculture, aviculture, designing, and telegraphy. The Germans appear to have interested themselves in languages, English and Spanish being specially favoured. Other subjects were shorthand, accounts, geography, and commerce, whilst technical instruction was also given in fruit and vegetable culture, forestry, chemistry, and mining. The aforesaid subjects cover a wide field, but only a limited number of students were able to avail themselves of the facilities offered. Funds for the above purposes were provided, directly by the Governments concerned, and indirectly by private individuals and public societies. To make provision for the needs of category 6, i.e. of officers and men wishing to continue their studies at the universities or schools of Switzerland, "L'Œuvre Universitaire Suisse" was founded in June, 1915, with a central office at Lausanne. This body assumed responsibility for the intellectual patronage of the Interned. In September, 1915, a decision was taken authorizing the Interned to follow university or college courses in the principal intellectual centres of the country, and local Committees of the "Œuvre" were formed for the purpose of assisting the students at the Universities of Bâle, Berne, Fribourg, Geneva, Lausanne, Neuchâtel, and Zürich.
