The $100 Prize Essay on the Cultivation of the Potato.: Prize offered by W. T. Wylie and awarded to D. H. Compton

In Short

Written by practical farmer D. A. Compton, this prize-winning treatise delivers a rigorous guide to cultivating potatoes in post-Civil War America. Compton walks readers through every stage of husbandry, detailing deep green-manuring cycles, seed selection, soil chemistry, and defense against ruinous blights and destructive beetles. Complemented by Professor Blot's precise culinary instructions and agricultural college trial data, the book endures as a vivid portrait of early scientific farming. It offers a rare window into an era when maximizing land yield was a matter of urgent national industry and surviving agricultural pests demanded constant vigilance.

The Story

Compton begins with an uncompromising defense of soil preparation, dismissing lazy agricultural habits and arguing that high yields require intensive planning. He details elaborate rotations of clover, plaster (gypsum), buckwheat, and rye, demonstrating how plowing under multiple green crops enriches and aerates the land. This systematic feeding of the earth serves as the foundation for all success, contrasting sharply with the destructive farming practices that deplete western soils.

Moving from ground preparation to the crop itself, Compton evaluates leading potato varieties of the era, weighing productivity, disease resistance, and flavor. He outlines the mechanics of plant reproduction, detailing how stamens and pistils interact so farmers can intentionally cross varieties to breed resilient stock. He then addresses planting mechanics, favoring precise cutting methods to preserve tissue around each eye, and analyzing how seed positioning along the tuber influences maturity and size.

The narrative turns sharply to the existential threats facing nineteenth-century farmers: disease and insect infestation. Compton analyzes the devastating potato rot of 1845, framing fungal blights as nature's mechanism for eliminating weakened stock. He champions gypsum and common salt as crucial chemical tools to fortify plant walls, regulate moisture during severe droughts, and deter parasitic growth. From microscopic fungi, he moves to macro-scale threats, cataloging destructive insects such as the Stalk Weevil, the Potato-Worm, the Three-Lined Leaf-Beetle, and the dreaded Colorado Potato-Bug. He details their life cycles, feeding habits, and natural predators, urging farmers to employ targeted chemical and manual interventions.

Harvesting and storage mark the next phase of the work. Compton warns against improper digging techniques that bruise tubers and stresses the absolute necessity of keeping harvested potatoes away from sunlight to prevent toxic greening and bitterness. He provides explicit instructions for field-curing and constructing straw-and-earth pits to carry the crop safely through harsh winter freezes.

The treatise expands its scope by incorporating expert contributions that take the potato from the field to the table and testing grounds. Professor Blot supplies detailed culinary recipes, asserting that cooking must be executed with the same precision as cultivation, whether preparing crisp Parisian fillets, light swelled potatoes, or savory Lyonnaise dishes. Finally, the book presents hard empirical data from the experimental farms of the Agricultural College of Pennsylvania, validating Compton’s methods through rigorous field trials on seed preparation, subsoil plowing, and sprout-thinning.

How It Unfolds

The soil is prepared Compton lays out a multi-crop rotation strategy, utilizing repeated sowings of clover, buckwheat, and gypsum to build deep humus, eradicate weeds, and create a loose, highly fertile seedbed.

The variety is chosen The author surveys popular varieties like Garnet Chili, Prince Albert, and Harrison, evaluating their yield, table quality, and resistance to disease while providing instructions on cross-breeding flowers for new strains.

The seed is planted Precise directions govern how tubers are cut to preserve flesh around each eye, warning against planting small, degraded stock and advising farmers to refresh seed stock annually from different soils.

The enemy is confronted The text examines the causes of potato rot and details the lifecycles of destructive pests like the Colorado Potato-Bug, advocating for the strategic application of plaster, salt, and protective field hygiene.

The harvest is secured Farmers learn safe digging procedures to prevent bruised tubers, followed by methods for curing in field heaps and constructing insulated straw-and-earth storage mounds to withstand winter.

The crop is served and verified Professor Blot presents refined cooking techniques for the table, while documented trials from the Agricultural College of Pennsylvania provide objective data supporting deep plowing and controlled seed preparation.

The People

D. A. Compton A self-described working farmer from Hawley, Pennsylvania, who "himself holds the plow." Compton wants to elevate farming from routine toil into a precise science, driven by intense practical observation, meticulous soil management, and a scorn for short-sighted, "parsimonious" agricultural methods.

Mr. Skinflint Compton's archetype of the careless, exploitative farmer. Skinflint neglects soil replenishment and relies on virgin land until it is completely exhausted, leaving fields that produce miserable yields of tiny tubers.

Professor Blot A culinary expert who contributes explicit recipes to ensure the harvested crop is prepared correctly, insisting that proper temperature, fat selection, and timing are essential to preserve the potato's table quality.

The Colorado Potato-Bug and Insect Pests Framed almost as active antagonists, these persistent beetles, weevils, and worms threaten the farmer's livelihood, forcing growers to master insect life cycles and deploy relentless defense measures to protect their fields.

The Agricultural Committee and College Researchers Prominent figures including W. T. Wylie, Mason C. Weld, A. S. Fuller, and Dr. F. M. Hexamer, alongside university experimenters, who evaluate, test, and validate practical farming methods through scientific trial and competition.

In Its Own Voice

"It is written by one who himself holds the plow, and who has, since his early youth, been engaged in agriculture in its various branches, to the exclusion of other pursuits."

Compton introduces his authority not through abstract scholarship, but through a lifetime of direct labor in the soil.

"A few hours' strong sunshine will ruin the best potato ever grown."

This stark warning underscores the extreme care required during harvest, explaining how light exposure renders tubers bitter and unpalatable.

"The country is becoming so 'buggy' that eternal vigilance is the price of every thing produced from the soil."

Writing at a time of rising agricultural pest outbreaks, Compton summarizes the constant struggle required of modern farmers.

What It's Really About

Beneath its practical instructions on plowing and planting, the book argues for stewardship over exploitation. Compton attacks the reckless depletion of American soil, contrasting exhausted Western fields with enriched Eastern acreage to demonstrate that land returns only what a farmer invests in it.

The text reflects a transformative moment when agriculture was shifting from traditional folk habits to scientific methodology. By exploring botanical anatomy, plant pathology, and chemical interactions like gypsum’s impact on plant physiology, the manual frames farming as an intellectual pursuit. It argues that success requires understanding natural laws, respecting plant hygiene, and accepting that dynamic threats—from fungal spores to invasive beetles—demand continuous adaptation and scientific rigour.
