New York, April 19- Edward Dorking, an English boy who was on his way aboard the Titanic to an Illinois farm and who saved himself by jumping from the deck, told today of the last minutes of the doomed vessel. "Three of us young fellows were standing together in a corner near the stern. We did not want to die. We knelt and prayed, then together we mounted the rail and plunged over. The water was frightfully cold. As the boat sank lower and lower behind us we saw something bobbing about on the waves far ahead. We made for it. It proved to be a raft. My head was just going below the water when a wave picked me up and dumped me within reaching distance of the raft."
