In Chapter 18, Anne and the Admiral are walking together and he's telling her how he and Mrs. Croft are enjoying Bath. He compares their lodgings to some they had in North Yarmouth, and ends by saying: "The wind blows through one of the cupboards just in the same way."

What does he mean? We live in a 1912 Craftsman bungalow in California, which had a built-in "cooling system" in one of the cupboards (a floor-to-ceiling corner cupboard with an outside wall, that had a screened opening at the top and bottom, and slatted shelves for air circulation, in which to place foods to be kept cool) up until 2 years ago, when we had the kitchen remodeled. Would this be what the Admiral is referring to?
