"It will be
interesting if we first describe this rye grass crop and the preceding
crop. A crop of wheat was grown in this field of seven acres last year,
and by the end of September it was well cultivated and sown with rye
grass seed. Three crops before this have been cut this year, the weight
of which was about eight tons to the acre for each crop, and as the
selling price was 1s. 6d. (36 cents) per cwt., this was at the rate of
L12 ($60) per acre per crop, or L36 per acre for the three crops. Had
not the last crop been set apart for the reaper and mower trials, it
would have been cut three weeks ago, when there were again about eight
tons to the acre. As it was, however, last week the crop had gone too
much to seed, and was too much laid for being of prime quality; the
result of which is, Mr. Tough, the owner, reckons the plants are too
much spent to stand well through a second year, and he therefore
contemplates turning it over in the spring for mangolds. Mr. Tough
calculated, however, that there were ten tons to the acre this cut, and
lots of carts and vans came to take the best of it; that is, the parts
which were not laid and yellow at the bottom, at the same price, 1s. 6d.
per cwt. The carts are weighed in over a weigh-bridge, and weighed out
again after the buyers have loaded up as much as they choose or require.
We may add this is better than selling by square measure. As to the next
growth, Mr. Tough says he shall get two more fair cuts this autumn if
the weather be warm, and he expects the two together will weigh eight
tons per acre more. As there will be a certain sale for this at 1s. 6d.
per cwt., this year's yield will realize the great return of L60 ($300)
per acre.

INFLUENCE OF WHITE COLORS.

Prof. Wallace gave at Glasgow some curious speculations based upon the
peculiarities observable in white animals. He had been discussing at
great length and with rare knowledge the distribution of butterflies,
remarking that some of the island groups were noticeably light-colored,
and endeavored to connect their color with their environment as follows:

Some very curious physiological facts, bearing upon the presence or
absence of white colors in the higher animals, have lately been adduced
by Dr. Ogle. It has been found that a colored or dark pigment in the
olfactory region of the nostrils is essential to perfect smell, and this
pigment is rarely deficient except when the whole animal is pure white.
