perish; especially if gutters (which is a general fault in builders) be made to run upon the principal rafters, the ruin may be sudden. Our sea-service for oak, and the wars in the North Sea, make timber at present of excessive price. I suppose, ere long, we must have recourse to the West Indies, where most excellent timber may be had for cutting and fetching. Our tiles are ill made, and our slates not good: lead is certainly the best and lightest covering, and being of our own growth and manufacture, and lasting, if properly laid, for many hundred years, is, without question, the most preferable; though I will not deny but an excellent tile may be made to be very durable: our artisans are not yet instructed in it, and it is not soon done to inform them.... Now, if the churches could hold each 2,000, it would yet be very short of the necessary supply. The churches, therefore, must be large; but still, in our reformed religion it should seem vain to make a parish church larger than that all who are present can both hear and see. The Romanists, indeed, may build larger churches; it is enough if they hear the murmur of the Mass, and see the elevation of the Host; but ours are to be fitted for auditories. I can hardly think it practicable to make a single room so capacious, with pews and galleries, as to hold above 2,000 persons, and all to hear the service, and both to hear distinctly, and see the preacher. I endeavoured to effect this in building the parish Church of S. James, Westminster, which, I presume, is the most capacious, with these qualifications, that hath yet been built; and yet, at a solemn time, when the church was much crowded, I could not discern from a gallery that 2,000 were present. In this church I mention, though very broad, and the middle nave arched up, yet as there are no walls of a second order, nor lanterns, nor buttresses, but the whole roof rests upon the pillars, as do also the galleries, I think it may be found beautiful and convenient, and, as such, the cheapest of any form I could invent.
