The author points to the very decided success of artificial, 
systematic pisciculture in America. Exhausted rivers have been 
re-stocked and brought back to their original state, and the public, 
who were at first apathetic and ignorant, have now come to take 
an intelligent interest in fish-preservation. Why cannot equally 
satisfactory results be reached here ? 
Among the enemies of the oyster-fisheries the author mentions 
the star-fish and the dog-whelk. Of the former he had last year 
to remove between 200 and 300 tons to prevent the bed being 
entirely destroyed. He has known a mussel-bed of 10 acres 
destroyed by these depredators in a fortnight. 
The Progress of Science. Vol. I., No. 1. May, 1881. Boston: 
45, Pearl Street, Boston, U.S. 
We have here the first number of a new scientific organ, which, 
according to an editorial notice, is to be “ devoted as far as prac- 
ticable to original investigations ; bold researches after rational 
truths, whether in fashion or out of fashion ; well-considered 
speculations indicating the direction of future scientific conquests, 
and hints, more or less full, as to the probable means by which 
the intimated results may be obtained.” 
The articles in this first number are — An Essay on Social 
Science, which scarcely lies within our legitimate scope ; a notice 
of the New Mode of Forcing Plants; a paper, singularly falla- 
cious as it seems to us, by J. B. Dimblely, on “ A Line of Astro- 
nomical Time from the Eclipses;” two articles on “Aerial 
Navigation,” an enterprise to which we cannot wish well, be- 
lieving that it will give a fearful advantage to aggressive war ; 
“ The Limits of Science,” by President D. W. Fisher; “ Bottled 
Daylight,” by Eric Stuart Bruce ; the commencement of a series 
of papers, by F. R. Condor, C.E., under the title “ What the 
World now asks from the Inventor;” “The Perihelia,” a memoir 
in which E. C. Carrigan ably exposes the alarmist predications of 
some great calamity to happen during the current year, in conse- 
quence of the relative positions of the planets. “ Godless 
Science ” is an extradt from the “ New Jerusalem Magazine.”
