Speaking at the Dominion Museum, Wellington, on the Samoan Observatory and tho seismological work dons there, Dr. C. E. Adams (Government Astronomer) said that tlio seismograph in usa there for recording earth tremors was such a delicate instrument that I>r. Angenheister, the director of the observatory, stated that ho could detect by it the effect of a cocoanut falling to the ground from the top of a cocoanut palm. When he (Dr. Adams) was on his visit of inspection to the observatory, H.M.S. New Zealand happened to enter Apia harbour, on tho shores which the observatory is located, and arrangements were made for him to witness taie effect on the seismograph of the shocks from the firing of hqj- salute. Professor Marsden stated that a very valuable series of seismological observations had "been made at tho observatory; and Dr. Angenheister was able to "tell not only where an earthquake had taken place, but also, to some extent, by means of the premonitory earth tremors, to predict the occurrence of the greater disturbances.
