 numbered " drift " bottles set free at times and localities 

 duly noted, and containing post cards to be filled in and 

 returned by the finder. As it had become desirable to 

 ascertain where fish eggs produced in the deep water off 

 Carnarvon and Cardigan Bays, the Welsh portion of our 

 extended district, would be carried to, I arranged to set 

 free a new series or' drift bottles during my passage down
