THE SEISMOGRAPH
A WONDERFUL INSTRUMENT. Speaking at the Dominion Museum last night on the Samoan Observattory and the seismological work done there, Dr C. E. Adams (Government Astronomer) said that the seismograph in use there for recording earth tremors was such a delicate instrument that Dr Angenheister, the director of the observatory, stated that h« could detect by it the effect of a cocoa-nut falling to tho ground from the top of a coeoanut palm. When ho (Dr* Adams) was on his visit of inspection to the observatory, H.M.S. New Zealand happened to enter Apia harbour, on the shores of which tho observatory is located, and arrangements were made for him to witness the effect on tho seismograph of tho shocks from the firing of her salute. Profe.ssor Marsden stated that a very valuable series of soismological observations had been made at the observatory : and Dr Angenheister was able to tell not" only where an earthquaka had taken place, but also, to soma extent, by means of the premonitory earth tremors, to predict the occurrence of tho greater disturbances.
