WATER FROLICS

'I would like to add my bif of information about diving dogs to your recent paragraph on the subject,' says Mrs. Barbara Collins, of Robertsbridge, in Sussex. 'While staying in Havana some years ago I walked along the Malecon, one side of which is lined with rocky cavities that the receding sea leaves full each time it visits the shore. I watched a collie dog for several minutes as it used one of the deeper pools in much the same manner humans would have done. It dived into the pool from one end of it, ,swam to the side, clambered out again, and repeated the por- formance again and again.' this sort of be- haviour on the part of animals which are evidently enjoying themselves in the fashion of humans is always fascinating. A keen sea trout angler told me the other day how his evening's sport was ruined by a family of otters that began shooting into the water down a bank, getting out and doing the same thing over and over. The game continued until all the sea trout were scared out of the pool and it was too dark to see the otters.
