show that a near approach to uniformity has been attained. Below is given a list of stations observed this year, with their latitudes and longitudes, and also tables showing the various values obtained for the secular variation of the magnetic inclination, horizontal force, and declination, as found from the seven repeated stations. These values will enable the results of observations made in 1901 and previously to be corrected for secular change, and so reduced to the epoch of the survey. The value (+ 1-91' per annum) found for the secular change of inclination is in the same direction but slightly larger than that (+ 1-41' per annum) found from the observations in various NewZealand ports made by Captain Stokes in the middle of last century. At Rotorua the change of magnetic declination has been remarkably small compared with that at the other stations. The mean resulting value for the annual change of declination in the North Island is approximately the same as that found for the South Island by observations at the Magnetic Observatory. Again, the value found for the secular change per annum of the horizontal magnetic force in the North Island is identical with that previously found in the South Island. By the courtesy of the Telegraph Department we were enabled to receive telegraphic timesignals from Wellington Observatory at many stations, serving as valuable checks on the local observations. That the value of the survey to science is recognised in scientific circles is shown by the following extract from a letter written by Dr. Glazebrook, Director of the British National Physical Laboratory, to the Agent-General for New Zealand. In it he says, " I have the honour to inform you that Mr. C. Coleridge Farr's statement of his work on the magnetic survey of New Zealand was laid before the Committee of the Laboratory at their last meeting, and I was instructed to convey to you for transmission to the proper quarter an expression of the high value which the Committee attach to Mr. Farr's work. It has been carried out with great care and skill, and at the present moment, when the antarctic expedition is at work in the extreme South, the results arrived at are of very real value to science. I gathered from a letter from Mr. Farr that he was anxious that the loan of the instruments should be continued beyond the period already fixed. In view of the value of the results, the Committee have great pleasure in continuing the loan on the same terms as heretofore for two years from June 30, 1902. The Committee would wish the instruments to be completely at Mr. Farr's disposal for the further period." Further on in the same letter Dr. Glazebrook suggests that when the work is completed the full report should be communicated to the Royal Society. It is hoped to observe at a number of stations in the interior of the South Island before July, 1904. When the field-work of the survey is completed, the reduction of the values obtained to the epoch of the survey will take a considerable time. At the request of the Nautical Adviser to the Government, a copy of the report forwarded to Dr. Glazebrook has been sent to him also, and he is using the corrected values of the magnetic elements in the compilation of course instructions for navigators, for incorporation in the New Zealand Almanac. In conclusion, it is a pleasure to acknowledge the unfailing courtesy and kindly interest invariably shown by officers of the Lands and Survey Department.
