in the tale there is only one river , and niniel follows the stream up through the woods and casts herself over the falls of silver bowl ( in the place afterwards called nen girith ) , and here too , in the glade above the falls , turambar slew himself ; in the developed story her death-leap was into the ravine of teiglin at cabed-en-aras , the deer 's leap , near the spot where turambar lay beside glaurung , and here turambar 's death took place also .
