Dear Mr. Williams,
I am writing on behalf of the English Department to invite you to give a lecture in our college. We know that you are an expert on American literature. As English majors, our students would like to know something about American literature. We would be very grateful if you could give a talk on "Contemporary American Literature" to students of the English Department on Saturday, June 4. If this subject does not suit you, any other similar topic would be welcome as well.
We have already had several very interesting talks from some distinguished visitors from various countries and we look forward early to the opportunity to benefit from your experience and wisdom.
