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.
