Work on the ND telescope is progressing at full speed both in Europe and on its location at La Silla. During September and October this year there was extensive preparation of the ground and roads on La Silla. Civil engineering Work began on the small hili next to the 3.6-m telescope at the place which was used during the past years for the Geneva Observatory Telescope. About 3000 m3 of earth was removed by means of a sequence of minor and finely Controlled dynamite explosions. Figure 1 shows the Chilean workers in the process of checking the locations of 28 explosions. The picture also shows their precautions to avoid excessive damage to the surrounding area. Large lorry tyres are placed on the ground and a strong metallic net is used as a protective cover. Figure 2 shows the explosion some minutes later. The smoke on the top of the hili indicates the future location of the ND.
