Income and Expenses.—­All our lectures are usually delivered in the same hall, built for the purpose.  It will hold 1,200 persons; 900 are thought a large assembly.  The expenses of rent, lights, doorkeeper, &c. for this hall, would be $12 each lecture.  The price of $3 is the least that might be demanded for a single ticket of admission to the course,—­perhaps $4; $5 for a ticket admitting a gentleman and lady.  So let us suppose we have 900 persons paying $3 each, or $2,700.  If it should happen, as did in Prof.  Silliman’s case, that many more than 900 tickets were sold, it would be easy to give the course in the day and in the evening, an expedient sometimes practised to divide an audience, and because it is a great convenience to many to choose their time.  If the lectures succeed in Boston, their success is insured at Salem, a town thirteen miles off, with a population of 15,000.  They might, perhaps, be repeated at Cambridge, three miles from Boston, and probably at Philadelphia, thirty-six hours distant.

At New York anything literary has hitherto had no favor.  The lectures might be fifteen or sixteen in number, of about an hour each.  They might be delivered, one or two in each week.  And if they met with sudden success, it would be easy to carry on the course simultaneously at Salem, and Cambridge, and in the city.  They must be delivered in the winter.

Another plan suggested in addition to this.  A gentleman here is giving a course of lectures on English literature to a private class of ladies, at $10 to each subscriber.  There is no doubt, were you so disposed, you might turn to account any writings in the bottom of your portfolio, by reading lectures to such a class, or, still better, by speaking.

Expense of Living.—­You may travel in this country for $4 to $4.50 a day.  You may board in Boston in a “gigmanic” style for $8 per week, including all domestic expenses.  Eight dollars per week is the board paid by the permanent residents at the Tremont House,—­probably the best hotel in North America.  There, and at the best hotels in New York, the lodger for a few days pays at the rate of $1.50 per day.  Twice eight dollars would provide a gentleman and lady with board, chamber, and private parlor, at a fashionable boardinghouse.  In the country, of course, the expenses are two thirds less.  These are rates of expense where economy is not studied.  I think the Liverpool and New York packets demand $150 of the passenger, and their accommodations are perfect. (N.B.—­I set down all sums in dollars.  You may commonly reckon a pound sterling worth $4.80.) “The man is certain of success,” say those I talk with, “for one winter, but not afterwards.”  That supposes no extraordinary merit in the lectures, and only regards you in your leonine aspect.  However, it was suggested that, if Mr. C. would undertake a Journal of which we have talked much, but which we have never yet produced, he would do us great service,
