348 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



since our coast waters seem to possess all the necessary conditions for 

 the propagation of this fish and for its development; and finally, because 

 for this culture one of our vessels could easily be prepared, thus avoid- 

 ing, at least for the present, the necessity of building more costly appa- 

 ratus on land. Such a vessel, if stationed at Nienwediep, could certainly 

 be employed under the most favorable conditions, because there are in 

 that place many cod-fishermen and an abundance of excellent sea-water. 

 If any one desires to study the construction and arrangements of such 

 a vessel, he can do no better than visit the American exhibit in the 

 London Fishery Exposition, where he will see excellent models of the 

 American vessels and other apparatus employed in fish-culture. 



I have mentioned above that as regards the salmon, whose culture — 

 thanks to private enterprise — is in good hands iu our country, it may 

 for the present be left in these hands, thus freeing the Government from 

 this responsibility. 



I cannot conclude my article without once more directing attention 

 to the circumstance that if we seriously think of having the third part 

 of the programme of the American Commission, viz, the propaga- 

 tion of food-fish, placed in charge of our Government, we must by no 

 means lose sight of the first and second part. With this view America 

 has established a zoological station at Wood's Holl. Also in the Neth- 

 erl.mds the establishment of such a station — much of whose work would 

 prove of great benefit to the fisheries and fish-culture — would lead to 

 a harmonious co operation of science and practice, which could not fail 

 to bear rich fruit and to increase the general well-being of our nation. 



If after a number of years some one should again report on fish-cul- 

 ture in the Netherlands, let us hope that he will be able to present a 

 different picture from mine, and give a glowing account of a public in- 

 terest, no longer neglected, but advanced to such a degree as to prove 

 a blessing to our entire country. 



57.-AIV AI\AI,YWIS OF ARTESIA1V WELL WATER FROTI THE SHAD- 

 HATGOI1VG STATION AT HAVRE »E GRACE, MR. 



By FRED. W. TAYLOR. 



[Chemist of the Smithsonian Institution.] 



An examination of the specimen of water from an artesian well at 

 the Battery Station of the United States Fish Commission at Havre 

 de Grace, Md., shows it to be heavily charged with iron, lime, and 

 chlorides. Magnesia is also present in considerable quantity. The iron 

 ami lime are very heavy. Sulphuric? acid is present only as a trace.
