When Farmer Brown visits the city, he hears all kinds of mechanical noises—toots, whistles, sirens, jackhammers, different wheels—all amusingly spelled out for readers and listeners to imitate and illustrated in Brown's gentle, idiosyncratic style, employing a soft, rich wash of artfully muted colors with the shapes mildly defined by a scattering of minute dots. A worthy successor to Margaret Wise Brown's Noisy books. (Picture book. 3-6)
