The salary is $1,200, and the examination is 
on geographic projections, mathematics, and to- 
pographic drawing and lettering. 
Mr. ANDREW CARNEGIE has offered the fol- 
lowing sums for library buildings, on condition 
that the cities mentioned shall provide the 
cities and ten per cent. of the cost of the build- 
ings annually for maintenance: Richmond, 
Va., $100,000; Montgomery, Ala., $50,000; 
St. Joseph, Mo., $25,000; Johnstown, N. Y., 
$20,000; Ashtabula, Ohio, $15,000. 
Mr. Henry H. Rogers, of New York, has 
presented to the Millicent Library of Fair- 
haven, Mass., the water-works of that town, 
yielding an annual income of about $8,000. The 
Millicent Library was given to the town of 
Fairhaven in January, 1893, by the children of 
Mr. Rogers, in memory of their sister Millicent 
G. Rogers. 
By the will of Dr. Abbott Hodgman, his 
library is given to the New York Academy of 
Medicine. 
THE Milwaukee Public Museum has just ac- 
quired the Rud. J. Nunnemacher collection, 
containing a large series of Buddhist, Confu- 
cian, Taonist and other divinities from China, 
Japan, India, Burma, Siam and Northern 
Thibet, in terra cotta, wood, bronze and brass. 
We learn from the Astronomical Journal that 
Mr. A. F. Lindemann, of Sidmouth, England, 
has placed means at the disposition of the As- 
tronomische Gesellschaft to be administered by 
a committee consisting of H. Seeliger, EH. Weiss, 
G. Muller and H. Kreutz for the purpose of ac- 
celerating the work of calculation of comet- 
material from ancient times to the middle of 
the nineteenth century. The conditions are 
briefly as follows: An average amount of 100 
Marks (about $24) will be paid for definitive cal 
culation of the orbit of one of these comets, the 
award being lower for those requiring a rela- 
tively small amount of time and higher for 
those presenting especial difficulty. The award 
will be made to the first calculation which suf- 
ficed the requirements of a definitive computa- 
tion, but may be divided in case of simultaneous 
determinations. The committee will decide in 
each case whether the requirements are met 
and the amount of payment. A list of these

comets, some seventy in number, may be ob- 
tained from Dr. Kreutz, who should be com- 
municated with, in order that duplicate calcu- 
lations may be avoided. 
THE officers of Section D— Mechanical 
Science and HEngineering—American Associa- 
tion for the Advancement of Science, Pro- 
fessor Henry S. Jacoby and Mr. William 
Harry Jacks, have issued a circular in regard 
to the Denver meeting. It reads in part. 
The subjects which are appropriate for the Section 
relate more especially to the application of science 
and of scientific methods to the various engineering 
problems. 
It has been suggested that short papers be pre- 
sented, giving information regarding the following 
questions: Have you any experimental data which 
either confirm or throw doubt upon formulas or con- 
stants hitherto generally received? Have you any 
data upon subjects hitherto considered doubtful, as 
for example, the strength of unstayed surfaces ? What 
subjects should engineering laboratories undertake to 
investigate with a view to obtaining data which will 
be of general importance, and how would you propose 
to make such tests (including a description of the 
apparatus )? 
It is hoped that many brief résumés of investiga- 
tions or experiments relating to different subjects of 
interest to the Section may be offered for this meeting, 
and that the support of the Section will be shown by 
the offer of a larger number of appropriate papers than 
usual, especially by the Western members who have 
long urged a meeting in the far West. 
THE fifth annual meeting of the New York 
State Audubon Society was held in the American 
Museum of Natural History on the afternoon 
of March 8th. Addresses were announced by 
Dr. Frank M. Chapman of the Museum, Dr. T. 
S. Palmer, assistant-chief of the U. S. Biolog- 
ical Survey and Mr. Charles R. Skinner, State 
Superintendent of Public Instruction. 
In order to aid in the extension and further 
equipment of the Scientific Department, of Man- 
hattan College, New York City, Dr. J. M. 
Ferrer and a committee of the alumni society 
have organized a course of five evening lectures 
to be given in Carnegie Lyceum during the 
month of April. They have secured the coop- 
eration of men eminent in their respective de- 
partments, as will be seen from the following 
syllabus :
