The mob was now gathering in the northeast corner of the yard and yelling itself hoarse.
But the two points of view may not be mixed in the same sentence or the same paragraph. That the following sentence is wrong should be evident at a glance:
The Kellog-Haines Singing Party has been on the lyceum and chautauqua platform for eight years and have toured together the entire United States.
Confusion is often caused also by qualifying phrases intervening between subjects and their verbs. Thus:
The number of the strikers and of the members of the employment associations do not agree with the report made by the commission.
And sometimes one finds a plural verb wrongly used after the correlative terms either ... or and neither ... nor, as in the following:
Neither the mother of the children nor the aunt were held responsible for the accident.
Finally, one often finds reporters consistently using a singular verb after the expletive there. In fifty per cent of the cases the writers are wrong. Thus:
The briefest glance at the yard and premises would have shown that there was more than one in the conspiracy.
