. . . A zealous Christian, Mr. C. C. Crowston, had built for himself a gospel car on a Ford truck chassis. He gave the finished car to Mr. [E. K.] Bailey [died 21st June 1953]. And so through the highways and byways and rolling farmlands of Oregon went the Message of Life, clearly proclaimed through the boldly-lettered texts on the car's side:
"Prepare to meet thy God."
"Be sure your sin will find you out."
"The wages of sin is death but the Gift of God is eternal life."
"The blood of Jesus Christ His Son cleanseth us from all sin."
Appropriately, "I am the door" was lettered on the car door, and John 3: 16 occupied all of one side.

"THE BOLD INTRUDER." (A Tract)
"The Empire Builder,” such is the eloquent and descriptive title given to J. J. Hill, the king of railroad magnates. But he is gone! His accumulated wealth of $250,000,000 could not buy off the king of terrors. Nor could his name and notoriety abash the bold intruder. His death-chamber called together skilled and celebrated physicians, but they could not cope with the antagonist of life, nor wrest their patient from the tyrant's grasp.
As a poor boy, he started out in life's fair morning. When he soared high in the sky of financial success, he was envied, counted wise, shrewd, and far-seeing by those who estimate a man according to what he amasses. He passed out of time—hoary with age, burdened with the weight of years and enriched with vast and varied experience; but the place that knew him once shall know him no more forever. If his absence is eternal here, his presence over there is for ever.
Man's existence does not end with time, neither does it end with eternity. Here he appears, then disappears; there he appears, but never disappears.
Reader, how is it with you? Are you so engrossed with the many affairs of time that you are giving no thought to the overwhelming and weighty matters of eternity? If so, you are a thousand times more foolish than the poor Indian that traded off a fortune in nuggets of gold for a few brass buttons. C. C. CROWSTON.

The poems off CC Crowston were always published in “Help and Food…,” indicating that he fellowshipped with Grant brethren. He was also quoted a number of times by HAI in “The Continual Burnt Offering,” which seems to indicate the same. Yet, the brethrenpedia reference above puts him in a TW meeting, which his memorial in LOI would bear out.

With whom are we to understand he fellowshipped?
