England was slower to enter the American fur trade than France and the Dutch Republic, but as soon as English colonies were established, development companies learned that furs provided the best way for the colonists to remit value back to the mother country. Furs were being dispatched from Virginia soon after 1610, and the Plymouth Colony was sending substantial amounts of beaver to its London agents through the 1620s and 1630s. London merchants tried to take over France's fur trade in the St Lawrence River valley. Taking advantage of one of England's brief wars with France, Sir David Kirke captured Quebec in 1629 and brought the year's produce of furs back to London. Other English merchants also traded for furs around the Saint Lawrence River region in the 1630s, but these were officially discouraged. Such efforts ceased as France strengthened its presence in Canada. Meanwhile, the New England fur trade expanded, not only inland, but northward along the coast into the Bay of Fundy region. London's access to high-quality furs was greatly increased with the takeover of New Amsterdam, whereupon the fur trade of that colony (now called New York) fell into English hands with the 1667 Treaty of Breda .
