Table exhibiting the business of the office for the last eleven years, and

the necessity of an increase of permanent clerical force.

[blocks in formation]

The foregoing statistics exhibit a very large increase of business in this office for the last eleven years; and by reference to the table it will be seen that the increase for 1851 is in full proportion with former years. This accumulation of business has been provided for from time to time by Congress, in authorizing necessary additions to the examining force. This force for the present is deemed sufficient. But there are still departinents of the business and labor of the office which have increased in a corresponding ratio with the examinations, and no provision made by Congress to relieve them. Hence the suggestions in relation to an increase of clerical force, in the preceding pages.
