[32] The party probably reached the vicinity of Walnut Grove on the afternoon of the 21st. From this time to the morning of the 24th it is impossible to reconstruct Duran's exact route. However, in general he seems to have run south, perhaps through the Mokelumne system, as far as the region northwest of Stockton, and thence westward to Suisun Bay. [33] If, as Fr. Duran said, he bore east as close as possible to the dry land, then the most probable course was through Snodgrass Slough, past Deadhorse I. into the South Fork of the Mokelumne. He must have followed this stream downward to Potato Slough and perhaps Little Connection Slough to a junction with the main San Joaquin R. There is no continuous waterway farther east. Farther west the only feasible pathway is directly down the Mokelumne R., a course which does not fit the description given. The Nototemnes (to the right) may have lived on Staten I., or conceivably Bouldin I. The others--Yatchicomnes, Passasimas, and Mokelumnes--were on solid ground, east of the sloughs. Their habitat probably extended inland from the delta for some distance. We know that the Mokelumnes inhabited the river of that name for many miles upstream. [34] The sand dunes between Antioch and Oakley, extending some distance up Marsh Cr. The name is still current as applied to the land grant made to John Marsh. [35] The reader will observe immediately that the point of view of a soldier is very different from that of a priest. He will also note the irritation inspired in the soldier by the priest. Despite the lengthy apologies the soldier does not conceal his exasperation that he is subordinate to the priest and that he is not permitted to go where he wishes and explore as he sees fit. The criticism of Fr. Duran by Argüello must be viewed in this light. [36] Duran says merely that the Commandante (Argüello) had "gone ahead" and stopped at the mouth of the San Joaquin. He followed the "route agreed upon" and stopped at the mouth of the Sacramento. [37] From the 15th to the 22nd the account of Argüello agrees within reasonable limits with that of Duran. Differences in detail and emphasis are to be expected and do not reflect upon the veracity of either writer. For discussion of the route, reference may be made to the notes (22-34 above) to Father Duran's manuscript. [38] The route followed by Argüello cannot be traced in detail. He seems to have followed sloughs in a generally northwest direction until he came upon the main stream of the Sacramento somewhere east of Grand I. (Isla de los Quenemsias), perhaps near Isleton. The skirmish with the Christian fugitives must have occurred in the Walnut Grove area. [39] According to Duran the meeting took place at the eastern entrance to the Strait, near Martinez.
