Cleave many curved blocks thy wheel to round,

And let three spans its outmost orbit bound;

Whereon slow-rolling thy suspended wain,

Ten spans in breadth, may traverse firm the plain.

If hill or field supply a holm-oak bough

[84]Of bending figure like the downward plough,

Bear it away: this durable remains

While the strong steers in ridges cleave the plains:

If with firm nails [85]thy artist join the whole,

Affix the share-beam, and adapt the pole.
