The Wampanoags’ only domesticated animal at the time the Europeans arrived was the dog.[76] Later, those Indians who adopted European culture as part of their conversion to Christianity seem to have begun keeping the types of livestock—cattle, sheep, goats, pigs, chickens, etc.—brought by the settlers.[77] AGRICULTURE Horticulture was a major occupation of the Wampanoags from the spring until fall. Chief among their crops was the native American corn, _Zea mays_. Historical sources mention a number of colors—red, blue, yellow, and white.[78] Of the squashes and their relatives (all grouped into the family Cucurbitacae) there are mentioned pumpkins and cucumbers.[79] Also cultivated was the native American variety of tobacco, _Nicotiana rustica_.[80] Gardening was work done by women, except for tobacco growing, which was the business of men.[81] The implements of cultivation were such things as clam shell hoes, and fish were used for fertilizer. During the time that the corn was growing the women would weed it and protect it from birds. Watch houses might be built in the fields where the gardener or her older children would sit all day to frighten away birds.[82] Sometimes hawks were captured, tamed, and kept nearby the house in order to chase the other birds away from the corn fields.[83] Corn might be harvested green or allowed to ripen in the fields, depending upon the use for which it was intended. Green corn seems to have been a favorite food, and to get as much as possible two plantings might be made during a summer.[84] At harvest time the women gathered in the corn and prepared it for consumption or storage.[85] When preparing a new field the first step was to remove the forest cover. Trees were cut down, leaving only the stumps; the branches were burned on the spot. Ashes left from the burning enriched the soil. Gardens were then planted between the stumps.[86] A field thus prepared would gradually diminish in fertility over a period of years of continuous use, despite the addition of organic fertilizers (fish) with each planting. When this happened, the field was left fallow for a period of time, during which a cover of weeds and brush would develop. This cover was then burned off, the ashes worked into the soil, and the field planted again.[87] FOOD PROCESSING
