If you are ambitious--and I know you are--there may be a field for you in such a country.

With your qualifications, fortified by the fortune which I am happy enough to be able to leave you, you may dare much and go far.

Should I be alive when you return from your exploration in Northern South America, I may have the happiness of helping you to this or any other ambition, and I shall deem it a privilege to share it with you; but time is going on.

I am in my seventy-second year .
