The plot, the situation, and the model;
Consult upon a sure foundation,
Question surveyors, know our own estate,
How able such a work to undergo.
A careful leader sums what force he brings
To weigh against his opposite; or else
We fortify on paper, and in figures,
Using the names of men, instead of men:
Like one that draws the model of a house
Beyond his power to build it."
