GYPSUM, OR LAND PLASTER Is iindDulni'illy the liest and cheapest fertilizer in the world, and is absohitely neces- sary in {greater or less (|uantily t(j every sort of land. At present no man in the United States that has any claim to thj title of Farmer would he without J'laster, and thousands of tons are yea ly jKjured from the mines in Michigan and Fayetteville over the whole of the Union. We notice that, except in the oldest and best farming districts in Ontario, Plaster is used almost exclusively on the sandy soils. This is a mistake. Evidence given in connection with the great agricultural depression in England leaches us thai /icazy c/aj' laud should be more extensively used foi i;ra:ini^ and far more Plaster soion on it to make !^ood meadows. COMPOSITION. Clypsum is compo.scd of 83 parts of Lime, 46 of .Sulphuric .\cid, and 21 of Water of Crystalization. The fertilizing property of Land Plaster is entirely due to liyjisuni. This sub- stance when chemically pure is absolutely white, any coloring )'.iatter being due to impurities, such as clay-shade, limestone, etc. From evidence given before the Ontario Agricultural Conmiission, it was con- clusively i^roved that it is impossible to adulterate White Lund Plaster, for the simple reason that there is nothiog it would pay to adulterate it with, while the very color and e.xtra weight of grey plaster shows it is adulterated with limestone, clay-shade, etc., to what extent the chemist alone can tell. Therefore, in buying Land I'laster that is not ivhite, so much money is throion a'lvay on useless stone which has no fertilizing properties Init has got mixed with the ]iure Gypsum. GRAND RIVER GYPSUM Of the beds worked V)y the (iKAND Rivkr tlvi'SUM Company, Sir William Logan, F.R.S., in his geological report for 1866, states, regarding its qviality, that it is " exceptionally pure.''

The above adds thereotical proof to the practically known fact that the GRAND River Whitk is 25 per cent, purer than any other Land Plaster in our market. Results obtained at Ontario Scliooi of Agriculture, Guelph. From the fifth annual report of the above Institution, for 1879, we extract the following hgures and statements by the President, being the result of a number of careful experiments on manures and fertilizers at their Model Farm. From a perusal of this report it will be seen that Land Plaster, coupled ivith manure, is the best and cheapest fertilizer that exists. EXPERIMENT WITH WHEAT.— " Manures were applied April acth harrowed under 29th, and Lost Nation variety of wheat drilled over all on the 28th. Among results in July is stated ' farm-yard manure and salt early mixed was regular and /air average, the same mixed only on application had a fair exhibit, but not so bold as others. Early mixed farm-yard manure and Gypsum had above an average of jwints. ' " In the table of resulting crop, on page 26 of the President's rejiort, the result of ■ grain and straw per acre is found.

Did the soil wanL Gypsum (Land I'lasier)? Plot 2 received 500 lbs. per acre and gave fully two-thirds of plants, with bulbs equal to those from lime, and thus pro- ducing 214 bushels per acre, ox three times more than those unmamireii. Gypsum was mueh better than the salt in -^ccuring a good beard. PROFIT. In a conversation with an old farmer as to the value of Land Plaster for grass growing, he stated he universally obtained a ton more per acre from use of Plaster. Suppose that loo lbs are used to an acre, a ton would be sufficient for 20 acres, therefore, according to the old farmer, there would be an increased yiehi of 30 tons, which, at the price of $10, 'ivould be $200 clear gain. Professor R. C. Kedzie, of Michigan State Agricultural College, after experi- menting in the College Park, states: "At the rate of yield on the State Farm, every ton of Plaster returns a profit to the farmer of from $100 to $200 at the least calculation." Evidence given before Ontario Agricultural Commisdon, at Gait, Aug. 19, 1880. Mr, Jas. Cowan, of Waterloo township, testified that he had a farm of ccj acres, on which he had used guano, gypsum, coarse and fine ground bone manure, besides various other artificial fertilizers in small quantities, and from the employment of none of these but gypsum had he noticed any results: he had also experimented with salt without any apparent result. Without Gypsum he did not think he could have made more than one-half the money that he had done. Mr. Andrew Telfer, of South Dumfries, said he had obtained this year a hay crop a hundred per cent, greater with the use of (iypsum than his brother, on the adjoining farm without it, although the respective fields were similarly situated; he preferred //wt'/v ,i,'';v«W to coarsely ground plaster. Mr. Daniel Purely, of Paris, gave evidence to the effect that any ground he had ever seen plaster put on had been benefitted by it; he had used it with advantage on his farm, which was oi clay loam, with limestone bottom. Mr. Alex. Parry, of North Dumfries, testified to beneficial results olMained with plaster on clover, peas and turnips; and that the rapid growth of the latter, owing to the fertilizer, had this year protected the plants from the fly to a great extent. Other gentlemen gave evidence which, on the whole, went to prove that Gypsum in connection with barnyard manure is the 'leapest and best fertilizer that can be used. DIRECTIONS. In all cases, where it can be done, the application should i)e made in still weather, when the leaves are damp from dew or fog or from recent rains, so as to cause the dust to adhere to the plant. As a general rule, the best results will be obtained by the application of the plaster direct to the leaves and stems of the plant, as the rains will wash enough of it down to the roots. Still sowing with the seed will pay largely. LAWNS. — Apply early and during the season — 400 lbs. per acre will keep the grass luxuriant. RED CLOVER. — The most surprising effect from use of plaster upon any crop is upon red clover. First application, 150 to 300 lbs. to the acre after the first frost leaves the ground; the same where the clovtr has a year or more growth. Fifty pounds to acre for second crop. THE GRASSES.— 100 lbs to acre. CORN. — Sow a tablespoonful or more on the hill when the plant is three to four inches above ground. POTATOES. — Same as with corn. One part of paris green with 20 of plaster is a perfect remedy for potato bug, besides invigorating the plant. Thii mixture should be sifted on, and not handled. GRAIN. — 200 lbs. harrowed in.
