23-Year-Old Explorer Tracks Amazon -- Mr. Snow on his arrival at Liverpool yesterday. Mr. Sebastain Snow, 23-year-old Ex-Etonian, has arrived home in Britain after completing alone the 3,500-mile journey from the source of the Amazon to its mouth. He has been away 18 months, and because he was suffering from Maleria and Dysentery the actual Amazon tracking took 10 months. For nine weeks Mr. Snow lived by himself on Andes Glaciers, taking measurements of the movements of the Glaciers. His food was tinned soups, beans, potatoes and biscuits. He drank Tea.
