 Excursions to the museums and otlier points 

 of interest were conducted by young ladies of 

 Graz. In the unique Landes-Zeughaus of 

 1642 are 30,000 pieces, including weapons and 

 armor, still seen in the rough racks as origin- 

 ally placed for the use of the soldiers. 



On one evening an outing was taken in the 

 Hilmwald, where beside the lake, overhung 

 with hundreds of Chinese lanterns, the Abend- 

 essen was partaken of. The beauty of the 

 many-colored lights reflected from the surface 

 of the water, and the quaint folk-music of a 

 band of peasant minstrels added much to the 

 truly Austrian sociability of the evening. 



On another occasion the members of the 

 congress lunched together under the trees of a 



restaurant garden upon the Schlossberg and 

 then enjoyed the views of the distant Alps, be- 

 yond the plain of Graz, through which winds 

 the Mur, and nearer, the richly colored roofs 

 intersected by narrow streets and the great 

 city park, with its splendid trees. 



Fitting telegrams and addresses were made 

 in celebration of the eightieth birthday of His 

 Majesty the Emperor of Austria and the King 

 of Hungary. Among the excellent responses 

 to the toasts at the final banquet those of 

 President Jordan and Professor Blanchard 

 may be characterized as especially felicitous. 

 After the adjournment of the congress 120 

 members took part in the excursion to Triest 

 and thence by special steamer along the 

 mountainous coast of Dalmatia.
