nothing of geological interest could be seen. The Inspector of Mines* * * § states 
that the seam strikes north-westerly, and dips to the north-eastward at 
about 1 in 1. Coxf speaks of the occurrence in this locality of two seams 
respectively 3 ft. and 4 ft. thick, but these probably represent a local 
thickening of the seam above described. Coal is also reported to outcrop 
on the eastern bank of Matiri River nearly five miles above its junction 
with the Buller. 
Analyses made in the Dominion Laboratory of samples of coal from 
seams occurring in the Murchison district are as follows :—

The coals in all cases formed hard dense cokes. Nos. 1 and 2 were 
collected* by Cox, and are samples from the 3 ft. and 4 ft. seams on the 
north side of the Buller near Murchison. Nos. 3-6 are from the same 
locality. No. 7 is from the 4 ft. seam outcropping on the east bank of 
Maruia River, and worked during 1915-16 by Mr. R. Fairhall, of Newton 
Flat. 
The Geology of the Te Kuiti District, with Special Refer¬ 
ence to Coal Prospects. 
By J. Henderson, D.Sc., Mining Geologist, Geological Survey Department. 
Introduction. 
Work in the Te Kuiti district was begun late in January, 1917, and 
was continued until the middle of April. An area of country about 150 
square miles in extent, including parts of the survey districts of Orahiri, 
Mangaoronga, Otanake, and Pakaumanu, was examined in more or less 
detail. In addition, observations were made towards the western coast of 
the North Island along the roads from. Te Kuiti to Mokau, from Te Kuiti 
to Mairoa, and from Waitomo to Putake. 
The main object of the work was to ascertain whether coal-seams of 
workable thickness were likely to occur beneath the limestone beds so 
j 
abundantly developed throughout the district. Since a full report is in 
preparation, only a brief summary of the information obtained will here 
be given.
