By nightfall, Douglas is no better, and his family takes him outside in a cot, in the hope that he will be cooled by a wind. Finally, at twelve-thirty, Mr. Jonas makes a stop with his wagon where Douglas is sleeping and leaves him two bottles filled with air containing soothing vapor and smells from the tropics and moisture-filled areas, on the condition that he pass this favor on to someone else. The bottles of air appear to work, as Tom finds Douglas breathing the same refreshing air in and out of his nose. The next morning, the heat and the cicadas finally fade down with the coming of rain, and Douglas is well enough to write in his tablet again of his experience. Chapter 39 (The Magical Kitchen) — Douglas' grandma is renowned in the household for her divine cooking for the entire family. Aunt Rose, however, threatens this magic when she questions Grandma's methods of cooking, and later persuades Grandma to organize her kitchen, wear glasses, and read from a cookbook while cooking. This systematic cooking that results, however, destroys the uniqueness and magicalness of Grandma's dinners for the rest of the family. In response to this, Grandpa bids Aunt Rose good-bye, but Grandma appears to have lost her touch for cooking. While the rest of the members are awake in their beds, Douglas sneaks down to the kitchen and restores it back to its original chaos, getting rid of the glasses and the cookbook. The family heads downstairs to find that Grandma has reconnected with her cooking again as it was meant to be, and everyone enjoys a magnificent late dinner. The chapter closes with Douglas thinking on how he repaid Mr. Jonas by passing on his favor.
