stone came next to the chain of lakes west of Taraganika, and died 
nobly in harness. Well, we are sent to complete what these several 
travelers have begun. While they are content with having discovered 
lakes, I must be content with exploring these lakes and discovering their 
sources, and unraveling the complications of geographers at home. It 
isa mighty work, but a fourth of that work is already done.

— The Eucalyptus or Australian gum-tree continues to be largely 
planted in California not only for ornamental but also for economic pur- 
“aig A large forest of these trees has been planted by a company and 
is situated on the line of railroad between Los Angeles and Anaheim. 
A recent statement of the company’s affairs shows that it owns two hun- 
dred acres of fine land, on which are houses and other improvements. 
About one hundred and forty acres have been set out in Eucalyptus, con- 
taining about eighty thousand trees. Of these some thirty thousand are 
from nine to fifteen feet high. The total cost up to January Ist, includ- 
ing purchase of land, houses, teams, etc., is $12,523. The estimated ex- 
pense for the first year, prior to incorporating the company, was 
$12,750, the actual expense being less than the estimate. The present 
value of the property is from $40,000 to $60,000, and this at a total cost 
of $12,523. The remaining sixty acres will be set out by the 5th of 
May, after which time the expenses will be but little. At the start the 
estimated total cost for four years was $1,000 to $20,000 or 20 per cent. 
of the capital, which will be reduced, according to later estimates, to 
$16,000 or $18,000, and it is believed that at the end of four years the 
Property will be worth not less than $100,000. Only a few shares have 
changed hands during the year, and these at an advance equal to three 
Per cent. The plantation is owned by seventeen persons. The young 
trees (Eucalyptus) have been produced in greater numbers in California 
the past season than ever before, and are sold by the nurserymen at 
much lower prices than previously, with an increasing demand. 
ae An essay by Dr. C. F. Liitken on the fresh-water fishes of Brazil, 
including some interesting new genera and species, and illustrated with a 
number of exquisite plate and numerous fine wood-cuts, appears in the 
memoirs of the Royal Academy of Copenhagen. The work is based on 
collections made some years ago by Professor J- Reinhardt. The mem- 
oir will prove of a good deal of interest to American ichthyologists. 
— The veteran microscopist and naturalist, C. G. Ehrenberg, died m 
daly last, aged eighty-two. His intellectual activity remained et al 
shed almost to the last, and though he failed to interpret aright the 
Structure of the Infusoria, his zodlogical and micro-geological works 
Were still valuable and original. i
