Total in one year from one pair 219 



The third female race of the old dam, and the second of 

 the first litter, seldom breed the first year, but are early 

 breeders in. the spring following, when we might expect an 

 increase of the whole in proportion to the first pair, if pro- 

 perly attended to and protected. 



Hares, It is generally allowed, that hares are not more than one 



fourth as prolific as rabbits, notwithstanding, agreeable to 

 an experiment tried by Lord Ribblesdale, who enclosed a 

 pair of hares for one year, the offspring was (as J have been 

 credibly informed) 68 : these animals, could they be ex- 

 ported to Upper Canada with safety, and there protected 

 within enclosures for a few years, would soon after spread 

 over a large extent of country ; the fur is nearly as valuable 

 as that of the rabbit. 



Climate of la that part of Upper Canada within 45 degrees of 



pper ana a. nort j l latitude, and the southern and western boundaries, 

 the climate is nearly the same as that of England, a little 

 hotter a few days in summer, and a little colder a few days 

 in winter, according to Fahrenheit's thermometer, which I 

 have paid great attention to for some years, comparing the 

 same with the observations of the English. 



Animals in- The increase of most animals appears much greater in 



creaso fast in proportion in America than in England, mankind not ex- 

 cepted. That of sheep is very apparent to those that pay 

 attention to their breeding stock, which gives me hopes, that 

 in a few years we shall be able to pay for our woollen cloths 

 in wool. Finding the effect of soil and climate so salutary 

 to sheep, &c, it may be reasonably supposed, that rabbits 

 will answer the most sanguine expectations; as I understand 

 the wool of the sheep retains all its nature the same as in 



England,
