THERMAL ACTIVITY.

r. E M A R K A B Lli DISCOLOURATION OF LAKE ROTORUA.

- [per press association.] i Wellington, Feb. 8. i Unusual thermal activity has been noticed recently in Lake Rutoma- • Lana, the centre of the great eruption of 188(5. The matter was speeii ally reported by Guide Warbrick, of Tourist Department, who for- ' ward -d full details-to the Minister ; in charge of Tourist Resorts (Hon. ; T. McKenzie,. The lake was discoL . soured about the middle of January. i being changed from a beautiful opal . I tint to a muddy yellow. The guide, i ! m making his visit of inspection. ; to ind that the colour on January I I isrh bad changed to a thick muddy ! brown. He steered a course up the f i lak- along the south shore, passing i the island on the way to the Mai- . ' mangu end. On going past the Awa- . ! rua St earning Cliff fresh activity was i noticed. The water was circling ■ round, bringing to the surface very : muddy wat *r. Further along, near the site of the fatiois pink terraces. I which were destroyed in the erup- ! tion. a frosh break <yn the surface i 'was ttot'i-rd. aril slate-coloured mud i was coming to the surface. "From I here.'' continues the report, "it took !a straight course down the lake, go- : ing along the cen‘re. '•• hen near the i island I found that, although the

t d-'pth was 3'J feet, the water was i ouit • warm, whereas the water i round the island has been cohl this i last ten years. T now come to the ; coni-hi-doti that the camo of the disi colouring of the lake is not far from ! the island. I cruised round for some jtime a-.'i found that th? lake was I quite warm from the north side of ■the island to the mainland on the i north side of the hike. I then returned to th? island and steamed all round it and up and down the lake, i but as th? lake was somewhat rough i nothing could lie noticed to indicate j wr.ere the actual spot of fresh ac- i tivity is going on. I feel quite certain that the bottom of the lake for a length of about two miles is now in a state of activity, but I don’t consider that there E at present any reason for alarm.” ‘ LAKE BACK TO NORMAL. Rotorua. Fell. 9. In reference to Guide M arbriek’s report on Lake Rotomahana.’the unusual thermal activity was noticed about the middle of January and has now ceased. The lake is now practically back to its normal colour, regaining claritv e very day. The only noticeable feature in the neighbour lined is more than usual activity in Waiinangn basin.
