Street Nomenclature.
The committee on street nomenclature held a meeting last evening, and adopted a resolution providing for the indexing of street names by which the duplications may be discovered. When corrections shall have been made, it is proposed that the index books shall be kept in the City Engineer's office, and the record kept up as each new street is named.
