The results of" Mr. Taunton's valuable experiments on tlie 

 eultivation of separate grasses, and the interesting leniarks 

 of Mr. Blaikie on the same subject, are in perfect confirma- 

 tion of the above statements, respecting the quantity of seed 

 to be used in cases where only one or two species of grass 

 are cultivated. Four bushels and a half of the above mix- 

 ture of grasses will give (omitting fractions) the same num- 

 ber of seeds to the square inch, as the like space of the sward 

 of the irrigated meadow contained plants, namely twelve: 

 now, after deducting for the deficiency caused by the num- 

 ber of barren seeds in many of those grasses, this quantity of 

 four and a half bushels per acre of this mixture of different 

 seeds, will be found for general practice not too much. The 

 practical trial before mentioned, proved precisely the truth 

 of the above calculations. But should the proportions of the 

 different kinds of seed be altered from the above, the quan- 

 tity of seed required for a given space of ground will be less 

 in proportion as the fertile-seeded grasses predominate in the 

 mixture : and the smaller the number of different species that 

 are combined together, the smaller will be the quantity of 

 seed per acre required, ten pecks being the maximum, and 

 two pecks the miiiimion. The above calculations of the num- 

 ber and weight of the different seeds, will afford a ready 

 guide to determine the number of plants of grasses which 

 will be produced on a given space of ground, from a known 

 weight or measure of the seed, whether it be of one species 

 of grass only, or of a combmation of many species. 



The larger seeds should be mixed by themselves, and, in 

 tile same manner, the smaller seeds should be mixed toge- 

 ther, and sown after the mixture of larger seeds, as they 

 require much less covering. The separation of the larger 

 from the smaller grass seeds, when mixed, can be readily 

 effected by a proper sieve. 



I have sown the seeds of the same grasses in every month 

 of the year, January excepted: and though much depends 

 on the weather and the state of the ground, the results were 

 always in favour of the month of September and the begin- 

 ning of Angust ; and, next to that, the middle or latter end 

 of May, according as the weather was dry. The seeds vege-
