Nezij Zealand in the Ice Age. — Hitchcock. 2yj 
two parts ; the highest commencing- as neve upon the west flank 
of Mt. Septon, and running parallel with the main glacier for 
four miles, and supplying it with avalanches along its whole 
course, nowhere touching the lower body. The precipices over 
which the ice falls vary in hight from 200 to 1,500 feet, over 
which avalanches fall from twenty to twenty-five feet every 
hour. Arrows upon the map indicate the general direction of 
this movement. 
The Fox glacier has been explored considerably because it 
is the nearest of the west coast glaciers to settlements, and de- 
scends the nearest to the sea level (734 feet). Cook river of 
which the Fox is a tributary, is a "wide unsightly stretch of 
shingle flats covered with large masses of drift timber, through 
which the water meanders in numberless channels." At the 
mouth of the Fox branch these flats are two miles wide. Some 
of the moraine piles reach the hight of 1,500 feet. The prin- 
cipal tributary of the Fox is the \"ictoria glacier, whose term- 
inus is over a precipice one thousand feet high. The Fcx 
arises from the western slope of Alts. Haidinger and Tasman 
and is ten miles long with a remarkable local neve at its source. 
The terminal face is 756 feet high, and is covered by debris for 
fifty chains. It is said that the retreat from melting is apparent 
in the middle rather than at its end. ^Measurements in the win- 
ter showed a motion in this glacier from twenty-one to thirtv- 
one feet in twenty-eight days. Near the lower end there is a 
fine hot spring and a l)oulder thirty feet high and three hun- 
dred and fifty in circumference. Tony's rock, lower down, \.- 
156 feet high and has a diameter of 268 feet. In the Copeland 
valley Fitzgerald measured a boulder 300 by 200 by 100 feet in 
linear dimensions and "there were others still larger." There is 
a large tree growing upon the top of one. I have not seen any 
notice of any larger boulders than these are in any glaciated 
district, and their immense number interferes seriously with 
exploration. 
Observations upon the rate of motion of several of these 
glaciers have been made with care. ( )n the Tasman, in the sum- 
mer, the average daily rate was from ten to eighteen inches ; 
in the Murchison, the average daily rate was from one-half to 
seven or eight inches; on the Hooker, from i.i to 5.4 inches; 
on the Mueller from 4.1 to 9.6 inches. The Franz Joseph gla-
