The shad v:orl: — This feature of the yearns operations appears in 

 discouraging contrast to the otherwise successful season. In some 

 cases the hatcheries, even with the aid of the States, were unable to 

 secure as much as half the number of eggs collected in their respective 

 regions in the most unsuccessful previous season. On the Susque- 

 hanna River and tributaries the collections have gone steadih^ down 

 from 209,992,000 in 1898 to 8,456,000 in 1906; on the Delaware and its 

 tributaries they fell from 115,033,000 in 1901 to 242,000 in 1906; the 

 take in the Potomac and its tributaries ranged from 68,724,000 in 1898 

 to 86,370,000 in 1903, and down to 12,696,000 in 1906. These condi- 

 tions are emphasized by the fact that in the Albemarle Sound region 

 the collections dropped from 75,400,000 in 1901 to Q, 748,000 in 1905, 

 but sprang at once to 25,771,000 in 1906, the first j-ear of enforcement 

 of the new law restricting the number of seines and pound nets in the 

 sound and mouths of its tributaries. 



Besciie of fixhsH front overf owed lands. — This work, along the Mis- 

 sissippi and Illinois rivers, w^as conducted on the same large scale as 

 during the previous year. Owing to w^eather conditions, however, it 

 was more successful this season on the Illinois than on the Mississippi,
