Washburne extranha que Oppenheim, em seis meses de estudo, sem dispor de auxiliares, haja coberto uma área tres vezes maior que a que ele Washburne cobriu em tres anos, ajudado por varios assistentes. Suas palavras textuais são estas:
“The State of São Paulo has approximately the area
of Texas, but Washburne could spend only 3 years
