After the March to Finchley, the next print I engraved, was the Roast Reef of old England; which took its rise from a visit I paid to France the preceding year. The first time an Englishman goes from Dover to Calais, he must be struck with the different face of things at so little a distance.

By the fat friar, who stops the lean cook that is sinking under the weight of a vast sirloin of beef, and two of the military bearing off a great kettle of soup maigre, I meant to display to my own countrymen the striking difference between the food, priests, soldiers, &c. of two nations so contiguous, that in a clear day one coast may be seen from the other.
