Sam Broadbent’s imitation of a warble fly turns a failed routine inspection into an unexpected demonstration of practical skill. At Mr. Kay’s farm, six heifers repeatedly evaded James Herriot’s efforts to bring them into the barn for tuberculin testing. A young dog could not control them, but Sam’s precisely imitated insect sound changed their behavior and made the test possible. The episode sets formal veterinary work against a local ability that the official procedure could neither anticipate nor replace.

The inspection and its growing delay

Herriot arrives as a Local Veterinary Inspector, a role marked by a certificate identifying him as an inspector for the Ministry of Agriculture and Fisheries. Its routine duties include clinical examinations and tuberculin testing. The work depends not only on veterinary judgment but also on farmers having their animals ready at an appointed time. When cattle must be gathered from fields after the inspector arrives, brief delays accumulate; Herriot explains that ten minutes lost at each of six visits would put him an hour behind.

At Mr. Kay’s, the cattle in the stalls initially seem to promise a smooth call. Herriot and the farmer finish testing them quickly, only to learn that six young heifers remain. They are grazing at the far end of a large field, and the apparent efficiency of the visit gives way to a problem of gathering them. The change matters because the inspection’s timetable is now controlled by the animals’ response, not by the plan Herriot had made for his day.

Repeated attempts to gather the heifers

Mr. Kay and Herriot call to the heifers and coax them up the hill toward the barn. The animals approach without urgency, but at the doorway the leader turns and bolts downhill; the others follow. The men try again, and the pattern repeats, with one heifer breaking away and the rest charging after her. Their movement makes the attempt feel less like a controlled gathering than a game whose terms the cattle set.

The physical effort also exposes a mismatch between official expectations and the task itself. Herriot has dressed according to the Ministry’s instructions for inspectors, in a long oilskin coat and Wellington boots. On the steep climb under the sun, that prescribed outfit becomes uncomfortable and impractical. His concern is no longer simply that the test is taking longer than planned: he is repeatedly climbing the hill in clothes chosen to satisfy a standard that does not account for this particular work.

When Herriot asks whether anything else can be done, Mr. Kay suggests bringing out his young dog, while doubting that it will be much use. The shaggy dog runs behind the grazing heifers and briefly raises Herriot’s hopes. At the barn, however, it is kicked under the chin; when the cattle turn toward it, the dog retreats, and the heifers pursue it down the hill. The attempted solution reverses the expected roles: rather than driving the cattle, the dog becomes the one driven away. Herriot reaches the point of saying that he will have to leave the animals untested and face whatever response the Ministry may make.

Sam Broadbent’s intervention

Mr. Kay recognizes that the effort has reached a standstill and proposes calling Sam Broadbent, who works for a neighbor. His explanation is that Sam can imitate a fly, specifically a warble fly. Herriot finds the claim difficult to credit, particularly when Sam arrives with a bicycle and appears, at first, unlikely to offer an answer to the problem. The contrast between this unpromising introduction and the skill that follows makes the intervention a reversal rather than a predictable extension of the earlier attempts.

Sam walks forward, forms a circle with his thumb and forefinger, and places it to his lips. After arranging his cheeks and drawing breath, he produces a swelling buzz that Herriot mistakes, briefly, for the approach of an angry insect. The heifers’ response is immediate: their earlier relaxed manner gives way to anxiety, and they move up the hill together in a close group. The sound works not by making the cattle playful or by physically pushing them, but by changing what they appear to anticipate.

At the building, the men guide the heifers into position. Sam returns up the slope at his own unhurried pace, pauses, and repeats the sound with greater insistence. The cattle then rush into the barn, and Herriot closes the half door behind them. Even after they are inside, Sam gives a sharp blast without using his fingers; the heifers draw together at the far wall. The detail confirms that his ability is more than a trick that happens to startle them once: he can reproduce the sound and sustain its effect long enough for the animals to be secured.

Testing completed and the meaning of the skill

A few minutes after Sam has left, Herriot is clipping and injecting the heifers’ necks. The test that had seemed impossible is completed, and the inspection can proceed. Herriot tells Mr. Kay that what he witnessed seemed like magic and calls Sam’s ability a wonderful gift. The practical outcome is plain: the animals are gathered, confined, and available for the required work, where repeated calls, herding, and the dog had all failed.

Mr. Kay’s answer complicates Herriot’s admiration. He agrees that Sam can imitate a fly, but adds that it is the only thing Sam is good at. The comment distinguishes the extraordinary usefulness of one specialized ability from a broader judgment of the person who possesses it. The narrative does not expand on Sam’s life or offer an independent assessment of that judgment; it leaves the remark beside the successful demonstration, where it can qualify without erasing the achievement.

The incident also gives the routine inspection a small but pointed reversal. Herriot begins with official instructions, a schedule, and suitable professional clothing, yet these do not help him move the heifers. The decisive knowledge belongs instead to a man summoned from two fields away, whose unusual imitation succeeds where ordinary attempts have failed. The cattle are not merely background to an inspector’s work: their repeated escapes and final response determine the course of the visit. The episode’s humor rests on that change of authority, from planned procedure to an unexpected local skill, and on the gap between what the official task requires and what actually makes it possible.
