metropolitan dairyman, it must be admitted that she is neither bo good for a cheese or butter dairy 

 as some of the smaller breeds. In the former cnso, quantity of milk is the desideratum, -while in 

 the two latter it is quolity or richness. Were the Yorkshire cow employed either for the production 

 of cheese or butter, the refuse — whey, and butter milk, or skimmed milk — would be much greater 

 than that yielded by milk of a richer quality ; and, iu consequence of this, the profits would be 

 considerably diminished. In a milk dairy there is no refuse ; and should the consumers iu large 

 towns complain of the inferior quality of the milk sold to them, they should remember that they 

 can not enjoy the luxuries of the country and tliose of the town at one and the same time. The 

 consumer is entitled to be served with the milk as it comes from the cow ; but when he insists on 

 having grass milk iu the middle of winter, he has no reason to complain should his importunity 

 force the milk-seller to adopt the harmless device of counterfeiting an article to please his customer's 

 oye, by the infusion of a drop of burnt sugar, to give the milk the rich yellow appearance which it 

 usually possesses when the cows are fed on grass. — Mr. Haxton, in "How to Choose a Good Milk Cov).' 



Guano, Superphosphate of Lime, and Chafpel's Fertilizer for Wheat. — Last f^ill I ciit two acres 

 of corn off to seed down wheat. Part of the land was a mellow loam, and part of it stony — the 

 stone a gray sand stone. I measured it off into three pieces — two pieces half an acre each, the 

 other one acre, in the middle, and drilled in the wheat with one of Moore's patent grain drills, the 

 first week of October. On one-half an acre I sowed 150 pounds Peruvian guano before sowing; 

 on the other I sowed 160 pounds of superphosphate of lime one week after the wheat came up ; 

 and on the one acre piece 600 pounds of Chappell's fertilizer before drilling the wheat in. The 

 guano cost $4.50, besides preparing it for use; the superphosphate $4.80, and the fertilizer $8.60. 

 There was no manure of any other kind put on either piece. For want of barn room I did not cut 

 and put each lot separate ; I can not therefore state the yield as accurately as I would like. Last 

 fall I could see very little difference in either ]uece, bnt in the spring the guanoed piece had a darker 

 green appearance, and was thicker on the ground than either of the other pieces. When the v/heiit 

 came out iu head, the guano piece was about four inches taller than the others, and those who 

 helped cut it, with myself, say that there is about one-third more to the groimd than on either of 

 the others ; the wheat better filled, and a better yield of straw. 



Last fall I plowed in 160 pounds guano on three-foui'ths of an acre of corn stalk ground, where 

 I had corn two years in succession, the ground inclining to clay, and where the corn was the 

 smallest in the field. On a half acre, rather better land, I plowed in six large ox cart loads of 

 horse stable manure, kept under cover ; the land was also manured in the spring for the second 

 crop of corn. Between these two pieces I could see no difference in the wheat when cut, except 

 that the manured was riper two or three days sooner, owing, I suppose, to the land being higher. 

 The guano in both cases showed itself to the drill marks. 



My conclusion is, that guano is cheaper than manure for wheat, as it costs less per acre. We have 

 to pay |;1.50 for an ox cart load of manure in West Chester, and haul it three miles, which is worth 

 half a dollar more. When I haul wood to West Chester, I haul manure as a back load, or I could 

 not haul it for that price. I would prefer good barnyard manure to either of the other three, if I 

 could make enough on the farm for each field. But the farm being out of order when I purchased, 

 I can't make enough as yet, using, as I do, part of it for potatoes in the spring. I put some Pata- 

 gonian guano and superphosphate of lime in the furrow for potatoes, along side of manure this 

 spring, and when dug I may give you the results of the experiments. 



The kind of wheat raised was the Mediterranean, drilled one bushel and three pecks per acre. J.

Wood Gas in Germany. — ^Two years ago, Dr. Peter Koffer, in Munich, invented this kind of gas 

 for light ; but, in order to make impracticable by suitable apparatus, he invited to a share in his 

 invention Mr. E. R. Breisach, an eminent practical chemist iu Augsburg, to whom the merit is due 

 of having brought it to general use in many cities of Germany and Switzerland. Mr. BnEisAcn 

 published ii report in the Ausburg Allecjmeine Zeitung, 20th May lasi^ in wliich he says it is beyond 

 cavil that wood gas can be supplied and used on the largest scale. 'The streets of Bayrouth (a large 

 city iu Bavaria), arc lighted with that gas, and eye witnesses from all parts of the country, confirm 

 imanimously that in brilliancy it is far superior to coal gas. Tlie intensity of its light is solely 

 a.scribod to chemical ])urity. For my investigations here in Bayrouth, I have made use as well of 

 Bunsen's Photometer as of ordinary wax light, as I did in former investigations at Augsburg with 

 coal gas, and I found an average, as the result of fifteen experiments on different days, and at dif- 

 ferent Iiours of the day, tliat under a pressure of 6-7 millimetres, and with a breadth of flame of 

 21 lines, and a composition of gas of 5 feet per hour, 15 3-10 power of light is produced, while coal 

 gas, under the same conditions, yields only 10-12 light power. For private consumers it may be 

 agreeable to be informed that with flat burners, consuming 4 7-10 cubic feet per hour, they have a 

 light power.of 14 7-10, and with 3 1-10 cubic feet, a light power of 8. 



Should further experiments confirm the above statements, the use of wood gas will 

 become general in this country, where wood so abundantly abounds.
