Amboccelia umbonata, Con. was found in several 
beautifully preserved specimens. 
And one of the dorsal valves is marked on the outer 
surface by concentric rows of minute short interrupted 
radiating lines, and when magnified resembles very 
closely the figure of Spir if er prematura on plate 33 of 
Hall’s Pal., of N. Y., Pal. 4, fig. 32. Further study of 
these forms will probably develope interesting facts.

Avicula speciosa , Hall. This species 
is represented by several specimens 
small and large, some of quite large 
size, but showing the characteristics of 
the Portage representatives. 
This fact is especially interesting as 
the form has not been recorded from 
outside Portage rocks, and though this 
stratum is but a few feet below the base 
of the Portage, it is distinctly below 
and in the midst of characteristic Gene- 
see slate. 
It will be observed that this brings 
the species into the Hamilton Period. 
There are also some well marked plant- 
remains, one linear grass-like form, 
another sturdy branching form the re- 
lations of which have not been made 
out. 
The dip of the base of the Portage 
in one direction was determined. Three 
stations were examined a thousand 
feet apart, and in nearly a straight line 
running North and South, and the 
elevation of the base of the stratum A 
of the Portage determined relative to 
the level of the lake.

These being 1000 feet apart, the dip is nearly 50 
feet in 2000 feet. 
The first 1000 feet showing 28^ feet and the second 
1000 feet showing 22^ feet nearly. Thus the dip is 
not uniform, a fact further shown by a study of 
the rocks further South where the dip is much less, as 
was determined by careful survey of strata near the 
top of the Portage. 
The accompanying diagram shows the general na- 
ture of the section at the three stations XXXII., 
XXXIII., and XXXIV. The scale is one centimeter 
to the foot. C, and A, and lower part of B contain 
concretionary nodules of iron pyrites; A, and C, sand- 
stones, are separated by the shale B, which is more or 
I 9 I 
less arenacious and differs decidedly from the Genesee 
slate below, which is the characteristic mud shale, 
black, and very fine in texture with arenaceous streaks 
in it toward the top. 
The fossiliferous stratum whose fauna is described, 
is (l, lithologically scarcely defined from the shales 
above and below. 
THE TELEPHONE AMONG THE INDIANS. 
The United States Fish Commission has lately con- 
nected, by telephone, its Salmon Hatching Stations 
at Baird, on the McCloud river, California, with the 
establishment for breeding the California trout five 
miles further up the river and the apparatus is now 
in thoroughly good working order. The Indians look 
on in blank amazement and call the instrument the 
Klesch-teen , or speaking spirit. 
A REMARKABLE METEOR. 
By Edwin F. Sawyer. 
While engaged in recording meteors on the evening 
of Oct. 9th, I observed a very remarkable one at 
10 h. 25 m. C. M. T., low down in the east, which 
calls for special mention. My attention was first at- 
tracted to what appeared a stationary meteor > 1 
mag. near y (Gamma) Orionis, and of a deep orange 
color. While noting its accurate position, the meteor 
very slowly (motion hardly perceptible) began to de- 
scend towards the horizon, where it disappeared 
behind some houses. It remained perfectly stationary 
for at least a second after it was first observed, and it 
occupied 6 seconds in traversing an observed path of 
io°. The meteor’s brightness decreased slowly as it 
approached the point of disappearance being at this 
point of the 3d mag. No streak was observed. The ex- 
act point of appearance was at R.A. 76°+ 5 5 and it 
vanished at R.A. 76^° — 5 0 near p Orioms (Rigel). 
Duplicate observations of this meteor would be of 
value.

THE "YELLOWS” OF THE PEACH TREE. 
By Prof. T. J. Burrill, Illinois Industrial University. 
A peculiar disease of the peach tree known as 
the “ yellows,” has long been the scourge of the 
principal peach growing districts of our country. 
Its appearance somewhat recently, in Michigan, 
caused much alarm, and since its occurrence through- 
out great orchards in some of the best fruit districts 
of the State, special attention has been called to it. 
In “Science” for September 25th, 1880, page 162, 
there appeared an abstract of a paper read by me 
before the American Society of Microscopists at De- 
troit, upon the blight of pear and apple trees. In this 
j paper I expressed the opinion that the “ yellows ” of the 
peach tree would be found due to an organism similar 
i to that found to be the cause of the pear tree blight. 
This opinion was based upon r.iy knowledge of the 
latter disease, upon the thoroughly confirmed conta- 
gious character of the “yellows,” and upon the failure 
of competent investigators to find, after extended re-
