It is common to find a few errors in a textbook, but "Transportation" has so many mistakes - grammatical and otherwise -- that it compromises the accuracy of the book. Parts of it are difficult, if not impossible, to understand. Perhaps to sidestep the negative connotation of the phrase, "what the traffic will bear" - i.e., using a monopoly to take the customer for all he is worth -- the author buries its definition in this impenetrable piece of prose:
"The second meaning, which can be more conveniently expressed in a negative form and which is germane to this discussion, is that no service should be charged a price that it will not bear when, at a lower price, the service could be purchased" (page 106).
On page 119, the author multiplies $8.46 x 110 and gets $93.06. On page 212, the book confuses the student with, "the cost of labor was $14.4 billion or $0.264 cents of every revenue dollar." It should have read, "26 cents". Worse, the facsimile of a commercial invoice on page 340 -- displaying Cost, Insurance, and Freight -- shows Incoterms FAS instead of CIF; such an invoice would never make it past an alert customs official. The sample bill of lading on page 342 is a blank form. More useful would be a commercial invoice and B/L that correspond to the same shipment and are both filled out correctly.
