OverviewExcerpt from Bolet n del Instituto Geol gico de M xico Querr a observar en este lugar que no se debe hacer ning n reproche a Sapper, por errores que haya cometido; al contrario mencionar aqu otra vez que sus trabajos han sido fundamentales y admiro lo que Sapper ha efectuado no obstante los caminos increiblemente malos, la falta frecuente de alojamiento y la extensi n de los montes v rgenes en el Norte del Esta do. En los caminos pantanosos, donde uno tiene que andar casi en todas partes a pie en el lodo profundo producido por el suelo empapado, donde el fango cubre casi toda la roca, es muchas veces extremadamente dif cil hacer observaciones, 6 hasta s lo dirigir su atenci n al mismo tiempo a los obst culos en el camino y a la roca.
