Stern calculated that , with Beatrice as a passenger , he could carry seventy-five or eighty pounds of freight . The two rifles , ammunition , knives , ax , tools and provisions they packed into the skin sack Beatrice had prepared , weighed no more than sixty .

The barking motor almost drowned his voice .
