tide of diet ; as, while beef has more carbon to the pound, 

 the herring has more nitrogen, and is, therefore, more valua- 

 ble as a producer of bone, muscle, and brain. 19 A, Februa-

REAPPEARANCE OF A PECULIAR HERRING ON THE NORWAY 



COAST. 



According to a quotation in Land and Water, a kind of 

 herring, which had disappeared from the coast of Norway 

 since the beginning of the present century, has within the last 

 few days again made its appearance in such numbers in the 

 waters between the Swedish continent and the Norwegian 

 Whale Islands that the fish are described as being, in some 

 places, packed together like a wall. The previous scarcity 

 of this fish is ascribed to the fact that the fishermen formerly 

 used nets of too small mesh, so that the young brood were 

 captured together with the older fish. 2 A, Jan. 6, 1872, 7. 



USE OF FISH AS MANURE IN ENGLAND. 



The complaint that fish which should be used as food are 

 wasted by being converted into manure for worn-out lands 

 is made in England as well as the United States, attention 

 beins: called in Land and Water to the fact that, in the late 

 herring season, the catch was so great that the country for 

 miles and miles in extent was supplied with fish sold for ma- 

 nure at the rate of twelve to fifteen cents a bushel. 2 A, 

 March 9,1872,167. 



FOOD OF SHAD. 



The nature of the food of the shad has long been a prob- 

 lem, as, when ascending rivers in the spring, their stomachs 

 are generally found entirely empty. A communication by 

 Professor Leidy, published in the Proceedings of the Acad- 

 emy of Natural Sciences in Philadelphia in 1868, may tend 

 to throw some light on this subject. In this paper, which 

 bears date October 20, he states that he has just examined 

 specimens recently caught in Delaware and off the New Jer- 

 sey coast, and found the stomachs full of small fishes from 

 two to four inches in length, belonging to the species known 

 as sand-lances (Ammodytes Americanus), of which as many 

 as thirty were found in a single stomach. 2 D, 1868, 228.
