Clovers and How to Grow Them — Reading Notes

A Practical, Not Botanical, Focus

Shaw explicitly limits his scope to clovers "possessed of economic value," omitting ornamental or minor species. His treatment is utilitarian: he discusses each variety's role in farm rotation, soil preferences, and yield potential. For example, he notes that alfalfa hay fed to horses requires gradual introduction to avoid "too much of a laxity in the bowels, too free urination, and profuse sweating." Such detail—drawn from observation and station reports—keeps the text anchored in working farm conditions rather than botanical theory. The author's voice is that of an extension specialist, not a botanist.

Irrigation and Regional Variation

Shaw addresses irrigation with caution, warning that applying water "late or in excessive quantities" can induce a "sappy condition" that makes plants succumb to winter cold. He notes that on porous soils in hot weather, more water is needed, but that in some locations—like islands in the Yellowstone River—ground water is so near the surface that alfalfa gets enough moisture without irrigation. These observations show his awareness of regional differences across the U.S. and Canada, a key claim in his preface. He advises that the right amount of water "can only be ascertained by actual test," emphasizing local experimentation over blanket rules.

Feeding Alfalfa: Grain Supplements and Finish

Shaw provides specific feeding guidance: alfalfa alone does not produce enough fat or firmness for the best markets, so grain is needed. He claims that "one-half the amount of grain required for finishing along with carbonaceous fodder" will give equally good results when fed with alfalfa hay. He also notes that later cuttings are finer and leafier, making them more suitable for calves and sheep. For swine, he recommends combining alfalfa with sorghum in dry conditions where corn fails. These details reveal a writer who understands both animal nutrition and farm economics, drawing on station trials and practical experience.

Structure and Sources

The book's organization is consistent: each chapter follows the same sequence of topics, from history to renewing the stand. Shaw acknowledges his chief sources as "bulletins issued by the various experiment stations" and discussions in the agricultural press. Illustrations come from professors at Tennessee, Louisiana, and Oregon stations. This reliance on institutional research gives the text an authoritative, data-driven tone. The dedication—"To all persons who are or may be interested in the growing of clovers"—underscores its intended audience: practical farmers and agricultural students seeking a comprehensive, orderly reference.

Diction and Voice

Shaw's prose is direct and instructional, avoiding florid language. He uses phrases like "it is evident, therefore, that there is not only room for a book... but there is great need for it" to justify his project. His sentences are often long but clear, packed with conditional clauses: "When it is fed to them too freely at the first, it induces too much of a laxity..." This style mirrors the careful, conditional reasoning of agricultural science. He rarely uses first-person, preferring the passive or third-person, which lends an impersonal, expert authority. The result is a manual that feels both thorough and trustworthy.

Shaw's Clovers and How to Grow Them is best read as a period reference—a snapshot of early 20th-century agronomy grounded in station research and farmer experience. Readers interested in historical farming practices, the development of extension literature, or the specific challenges of clover cultivation will find it a methodical, evidence-based guide. The book's value lies not in novelty but in its comprehensive, orderly treatment of a single crop group across diverse North American conditions.

I kept thinking about Shaw’s clover manual long after closing it—the quiet patience in his rotations, the way he trusted soil to heal itself. It reminded me of drifting through The Book of the National Parks — Themes and Context, where preservation feels less like action and more like reverence. Both left me strangely settled, like a field left fallow, holding space for whatever comes next.
