The greater portion lies within the doab or level alluvial plain between the Ganges and the Jumna.
Save for hills in the distance, the country was as flat as any passed through while traveling over the doab and other sections.
We left Allahabad at noon, and travelled through the rich valley of the doab, 100 miles, to Cawnpore.
The names Punjab, doab, &c., show the root in a clearer shape.
Our brothers at Cawnpore may have secured Allahabad and other towns in the doab long ere to-day.
Farukhabad is one of the healthiest districts in the doab, but fevers are prevalent during August and September.
