Sauer aud Mosel. lu the Lower Mosel the salmon catch is satisfactory. 

 Baron von Diicker, at Menden, says that there are a good many salmon 

 in the Euhr as far as they couhl ascend in the long-continued low stage 

 of the water over the almost imi)assal)le dams on the Euhr (with a favor- 

 able stage of water they used to ascend as far as Herdecke), so that 

 the Westphalian flsh-culturists may have the satisfaction of asserting 

 that tbey have accomplished something. At Werden, for instance, sal- 

 mon of all sizes can be seen morning and evening continually leaping. 

 It is an interesting circumstance that at Witten, in September, Mr. 

 Carl Lohmann took aSJ-pound salmon in the Ruhr with an artificial fly, 

 a red i^alraer 20 millimeters long. At Hattiugen many salmon have been 

 taken — in the Schleuse, as the reporter says. We hope that the capture 

 is not accomplished in the same way as it used to be in the now abol- 

 ished trap at Miihlheim. In the Main salmon appear more plentiful 

 than formerly (report from Hammelburg). The greater part of the 

 Khine salmon are caught in Holland, and the most of them come to the 

 market of Kralings-veer. Since 1870, when the fish-breeding establish- 

 ment at Hiiuingeu came into German possession, a great number of 

 salmon fry have been turned out in the Rhine Valley. The following 

 table shows that since that time the salmon fishery has improved, though, 

 to be sure, it cannot be shown how much fish-culture has contributed to 

 it, since the final result is the j)roduct of sundry factors in part unknown.

For the months of October, November, and December, 1883, it is as- 

 sumed that the catch will average as in the thirteen years preceding. 

 It will be seen that 1883 is the best year since 1870, even exceeding 

 1874. 



From the Ems district Von der Wengen reports that in July of this- 

 year, in the Werse, at Muuster, the run of salmon was very good. The
