To C. Trebatius Testa on his way to Gaul, from Cumae, April or May 54 BC

For my part, I never cease recommending you, but I am eager to know from you how far my recommendation is of service. My chief hope is in Balbus, to whom I write about you with the greatest earnestness and frequency. It often excites my wonder that I don't hear from you as often as from my brother Quintus. In Britain I am told there is no gold or silver. If that turns out to be the case, I advise you to capture a war-chariot and hasten back to us at the earliest opportunity. But if—letting Britain alone—we can still obtain what we want, take care to get on intimate terms with Caesar. In that respect my brother will be of much use to you, so will Balbus, but most of all, believe me, your own modesty and industry. You have an imperator of the most liberal character, your age is exactly the best one for employment, and your recommendation at any rate is quite unique, so that all you have to fear is not doing yourself full justice.
