the death offish, as well as other animals, the better for us. 

 There is also some choice in the method of killing ; this, in 

 most cases, being by a violent blow on the head, or against 

 the side of a boat, or by means of a stick. The practice in 

 Holland, however, is to sever the spinal marrow and the ar- 

 teries of the neck just back of the head, by which means 

 death ensues immediately, and the blood is allowed to escape 

 from the body. 



The difference in the taste offish killed and of those allowed 

 to die is most marked in species of vigorous habits and con- 

 taining much blood, such as, for instance, our own bluefish 

 (Temnodon saltato?'). Many persons have been struck by 

 the excellence of this fish, as served up at Nantucket or Ed- 

 gartown, finding them so much superior to those which they 

 have eaten in other localities. The practice of the fishermen 

 in these waters is to cut the throat of the fish between the 

 gills immediately after capturing them, thus allowing the 

 blood to escape freely and in large quantity. Experience 

 has shown that fish killed in this way, and bled, will retain 

 their firmness and freshness very much longer than those al- 

 lowed to die in the ordinary manner. Zeitschrift fur AJcMi-

REMOVAL OF RUST SPOTS ON LINEN. 



It is said that spots of rust on linen or cotton articles may 

 be made to disappear by first dipping them in a boiling hot 

 saturated solution of oxalic acid, and then sprinkling them 

 with very fine tin filings. 5 (7, xx., 160. 



PREPARED CORN-COBS. 



A very convenient kindling wood is made in France from 

 corn-cobs by immersing them in a mixture of sixty parts of 

 melted resin and forty parts of tar, after which they are taken 

 out and allowed to dry. They are then subjected to a second 

 operation, which consists in spreading them out on a metallic 

 plate heated to 212 Fahrenheit. They are finally assorted 

 according to size, and tied up in bundles. These are sold at 

 the rate of three or four for a cent. The establishment in 

 Paris for manufacturing them employs thirty workmen, and 

 effects sales to the amount of $40,000 annually. 13(7,1871,
