Atkinson. 
Although Price was no longer present to criticize 
the design of the lower bearings on 622-type current 
meters, his earlier criticism was still valid and was 
Atkin- 
son accordingly took steps toward correcting the 
fault by redesigning the lower end of the hub assembly. 
In his modification, the lower bearing was set within 
a fairly deep cavity that was drilled into the lower 
end of the axle, thus reestablishing the type of air 
recognized as such by many Survey officials.

Atkinson improved upon and standardized the hard- 
ness of the metal used for the pivot and lower bearing. 
The following is an extract from an announcement 
about these alterations which was sent to field offices 
of the Survey on September 10, 1931: 
We now have seven meters with redesigned shaft assembly 
and pivot in the field. It is hoped that the field tests will 
have sufficiently progressed so that the results may be 
presented at the [forthcoming] conference. 
The field tests reported at the 1932 Water Re- 
sources Branch Conference were generally favorable, 
and Atkinson’s design was accordingly approved. 
It was identified by the Survey as the Type-A Small 
Price Current Meter and later by Gurley as their 
catalog no. 622—A. A drawing showing the details
