Cream 15.60 lbs. 



While curd cheese 8.93 " 



Whey 75.47 " 



100.00 



The 15.60 lbs. of cream yielded by churn- 



iflg: 



3.33 lbs. butter, or 21.2 per cent., and 

 12.27 " buttermilk. 



The reckoning with reference to 100 lbs. 



of milk consequently stands thus: 



Cheese 8.93 



Butter 3 a? 



Buttermilk 12.27 



Whey.. 75.47 



100.0 



Taking the whole of the milk obtained and 

 treated at different seasons of the year, I find 

 that 36,000 lbs. of milk yielded 1080 lbs. of 

 fresh butter, which is at the rate of 3 per 

 cent. From the statement of M. Baude, it 

 appears that near Geneva a proportion of 

 butter so high as 3 per cent, is never ob- 

 tained, probably because there a larger pro- 

 portion of fatty matter is left in the cheese. 

 In the dairy of Cartigny, 2200 gallons of 

 milk gave : 



Butter 363 lbs. or about 1.6 per cent. 



Grucyere Cheese 1515 " 6.9 " 



Clot from the whey, ob- 

 tained by boiling 1140 " 5.2 " 



In the same neighbourhood,'another dairy, 

 that of I,ullin, gave from the same quantity 

 of milk: 



Butter 418 lbs. or 1.9 per cent. 



Cheese 1485 " 6.75 " 



Clot from whey 968 " 44 " 



Safety in Thunder Storms. 



People are often led to inquire what are 

 the best means of safety during a thunder 

 storm. If out of doors, we should avoid trees 

 and elevated objects of every kind ; and if 

 the flash is instantly followed by the report, 

 which indicates that the cloud is very near, 

 a recumbent position is considered the safest. 

 We should avoid rivers, ponds, and all streams 

 of water, because water is a conductor, and 

 persons on the water in a boat would be most 

 prominent objects, and therefore most likely 

 to be struck by the lightning. If we are 

 within doors, the middle of a large carpeted 

 floor will be tolerably safe. We should avoid 

 the chimney ; for the iron about the grate, 

 the soot that often lines it, and the heated 

 and clarified air it contains, are tolerable 

 conductors, and should, on that account, be 

 avoided. It is never safe to sit near an open 

 window, because a draught of moist air is a 

 good conductor ; hence we should close the 

 windows on such occasions. In bed we are 

 comparatively safe, for the feathers and blan- 

 kets are bad conductors, and we are to a 

 certain extent insured in such a situation. 



Agricultural Premiums. 



At a stated meeting of the Philadelphia 

 Society for the Promotion of Agriculture, 

 held on the 7th inst. — Pres't. Doctor Mease 

 in the chair, 19 members present. 



The proceedings of last meeting were read 

 and ordered to be recorded. 



On motion of C. S. Smith, the premium 

 list for crops for the ensuing season was re- 

 considered, the quantity of ground and rate 

 of premium for each reduced as follows: 



For the best field of wheat, not less than 

 three acres, !?;8. 



For the best field of rye, not less than three 

 acres, ^8. 



For the best field of oats, not less than 

 three acres, !«8. 



For the best field of corn, not less than 

 five acres, ^8. 



For the best lot of potatoes, not less than 

 one acre, $5. 



For the best lot of sugar beets, not less 

 than half an acre, $5. 



For the best lot of ruta baga, not less than 

 half an acre, S5. 



For the best lot of carrots, not less than 

 quarter of an acre, 85. 



For the best lot of parsnips, not less than 

 quarter of an acre, .$-5. 



For the second best crop of each of the 

 above, a copy of Colman's Agricultural 

 Journal will be awarded. 



Several valuable books were presented to 

 the Society, amongst which were Ellsworth's 

 Reports, and the Transactions of the Russian 

 Imperial Economical Society of St. Peters- 

 burg. 



A box of Peruvian guano of superior qual- 

 ity, was presented for distribution by Mr. R. 

 P. Lardner, being part of a lot obtained by 

 Lieut. Lardner, on the coast of Peru.

Draining — Subsoil Ploughing. — Next in 



order to the drain succeeds the subsoil plough. 

 The water being drawn oft* the land, it will 

 bear to be deeper dng, or stirred or trenched. 

 The crops which formerly were condemned 

 to draw their sustenance from six or nine 

 inches of soil, can now descend 18 or 20 

 inches. A double store of food is thus un- 

 locked; and he who opens up, and, by drain- 

 insr, renders wholesome the surface of his 

 fields to a double depth, does, in reality, add 

 in effect to the available extent of his pos- 

 sessions. He makes them capable of yield- 

 ing him larger returns, and for a longer pe- 

 riod of years, witliout the risk of exhaustion.
