"Dr. H.N. Jackson and S.K.
Crocker Will Start this Morning on Automobile Trip They
Hope Will End in New York"
An automobile trip across the continent that will be watched with a great deal of interest will start from this city this morning. It will be undertaken by Dr. H. Nelson Jackson of Vermont and S.K. Crocker of Seattle, both of whom are at the Palace ready for the journey. All attempts heretofore to go overland in an automobile have come to grief either through the machines breaking down or because long stretches of sand were encountered through which the horseless carriages could make no headway.
Dr. Jackson is a man of wealth, who is very fond of automobiling. Mr. Crocker is a devotee of the new machines and expert as a chauffeur. He is also very handy at repairing, a faculty that may prove of value. Dr. Nelson has provided the very latest kind of gasoline machine, large and commodious and 20-horsepower. Enough gasoline can be carried to run the machine 250 miles.
Speaking last evening of the contemplated trip of himself and Mr. Crocker, Dr. Jackson said: "...we will sleep on matting under the automobile at night and carry ample food and cooking utensils. No one has ever crossed the continent in an automobile and we are anxious to succeed. The great trouble in the past has been that automobile parties trying to cross overland have struck sandy wastes through which a machine cannot be driven. We will take our own time and are satisfied we will get to NY, ourselves and machine a little bit the worse for wear. In a general way we will follow the route of the Oregon Short Line and then country roads and wild stretches of country along and adjacent to the line of the Union Pacific."

"I made the first cross-country trip"

North of Sacramento, we were lost.
We met a red-haired young woman riding along on a white horse.
"Which way to Marysville?" I asked her.
"Right down that road," she said and pointed. We took that road for about 50 miles and then it came to a dead end at an isolated farmhouse. The family all turned out to stare at us and told us we'd have to go back.
We went back, and met the red-haired young woman again.
"Why did you send us way down there?" I asked her.
"I wanted paw and maw and my husband to see you," she said. "They've never seen an automobile."

"This [rain] prevented our following the railroad, as we had intended doing; for the roads running parallel to it sloped toward the tracks and the water had banked up there until it was impossible to drive a vehicle through it. Then we had a dilemma. We use of cross roads wherever any favoring us were to be found; and whether they were not we took to the field or prairie and zigzagged as best we could. Sometimes we went north instead of east; at others we even went northwest, only to retrace our steps when the opportunity presented. Where the railroad went one mile we would frequently go five. This was kept up nearly all the way across Wyoming; and when we crossed Nebraska it became worse instead of better."
