Laboratory for analysis, so that their mineral contents can be compared with 

 those of well known springs in the northern hemisphere. I shall be truly 

 gratified should these few notes assist in drawing the attention of the Pro- 

 vincial Government of Nelson to the great treasure it possesses in these springs, 

 and that they may thus be made accessible to those of our suffering fellow 

 colonists, who have hitherto only been deprived from using them by the 

 neglected state in which they have been allowed to remain for years. 



Further Notes on the Thermal Springs of the Hanmer Plains, hy Dr. Hector.

"In reply to your request for any information I possess relative to the 

 hot spi-ings which occur on the Hanmer Plains, I beg to inform you that I 

 examined them on the 8th May, 1867, and made the following notes at the 

 time : — 



"The altitude of the springs above the sea I found to be 1360 feet, and 

 about 110 feet above the level of the neighbouring river. They occur on flat 

 terrace land, under the range of hills that bounds the valley on the north side 

 near where they are crossed by Jollie's Pass, leading to the Valley of the 

 Clarence. I made my observations early in the morning, the temperature of 

 the air being 52° F. 



" 1. A shallow muddy pool, twelve feet in diameter. Temperature, 50°5. 



" 2. At thirty feet distance from the above, and six feet lower, a pool of 

 circular form, six feet in diameter, and more than eight feet deep, has a steady 

 overflow and constant escape of bubbles of sulphurous steam. Temperature, 89°3. 



" 3. Twenty feet across, and seven feet deep close to the bank. Tempera- 

 ture, 89°5. 



"4. Eighteen feet across, and more than ten feet deep. Temperature, 88°5. 



" 5. Several small pools around the sides of the two last, had a tempera- 

 ture of 90°5. 



" There are, in all, three large holes and four small, the latter being about 

 four feet in diameter. 



" Four hundred yards to the east is an intensely green and cold spring, the 

 water of which has a temperature of 43°, while the water in the neighbouring 

 creek was 49°. 



" The terrace on which these springs occur is composed of gravel and sand, 

 and there is no appearance of any outcrop of rock nearer than the foot of the 

 spur, which is 400 yards distant. There is no large deposit of silica from these 

 springs as in the case of the geysers in the North Island. A small quantity 

 of the water from the hottest spring was obtained for analysis, and gave the
