After a 25 year postal veteran, I read with more than casual interest Assistant Postmaster General Frank S. Johnson Jr.'s letter (July 11) criticizing Daniel S. Greenberg's column (June 22) which said the U.S. Postal Service is medieval and in need of modernization.
In my opinion, both Johnson and Greenberg are right in what they claim but only to a limited degree.
As Johnson stated in his letter, the postal service has modernized the processing of mail during the last few years with the addition of such highly technical devices as various types of computers, optical character readers and other electronic machines. A short time ago, clerks were only able to process some 10,000 letters per hour by mechanization. Today, they are able to sort a much greater volume of mail at a greater rate of speed.
In addition, the window service has been partially computerized enabling the clerks to handle a larger amount of incoming mail.
Such complicated machines as the automated postal mailing station, which allows a patron to mail anything from a letter to a 35-pound package, are now being introduced into the system to speed up the servicing of mail.
While all this appears impressive, the nitty-gritty of the postal service--the delivery process--has not been improved for decades and it is still back in the 18th Century.
