243 EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



No. 12609. — From Pavilion, B.C. This deposit in an air-dried condition was of 

 a yellowish-grey colour, the mass being crumbly and friable, with the general appear- 

 ance of marl. The data show that this is a marl of excellent quality. 



ISlo. 13105.- — From the bed of a creek at Port Hope. As received, this was a 

 greyish-white pasty mass, containing many small shells. In addition to 80 per cent 

 carbonate of lime, the marl contains about 16 per cent vegetable organic matter, 

 which would enhance the value of the deposit for certain soils. 



No. 1S75S. — From Lower West river, Antigonish, N.S. A light yellowish-grey 

 earthy deposit, in powder and small lumps and having the appearance of weathered, 

 disintegrated limestone. Of fair quality. Its efficiency, no doubt, would be enhanced 

 by crushing. 



No. 14053. — From bottom of a lake near Ste. Luce, Eimouski, Que. As received, 

 was whitish-grey pasty mass; on drying, it was found to be friable and easily reducible 

 to powder. The analysis confirms the impression from its appearance — that it is a 

 marl of very fair quality. 



No. 1^102. — From Clydesdale, N.S. A yellowish-red, earthy deposit in lumps 

 of very considerable hardness. Analysis shows the presence of 85 per cent carbonate 

 of lime, but in order that this material might prove an efficient amendment it would 

 be necessary to reduce it to powder. 



No. 13813. — From the bottom of a lake near St. Jovite, Que. A light-grey, 

 earthy deposit, containing a good many small shells. A qualitative examination 

 showed very little insoluble matter and the sample was reported as a shell marl of 

 good quality. 



No. Ilf055. — From Hedley, B.C. This calcareous material, evidently formed by 

 deposition from water highly charged with lime, was submitted to qualitative analysis 

 and found to consist essentially of carbonate of lime. 



No. 11/.108. — From Consecon, Ont. As received, this was greyish-white and showed 

 little or no admixture with clay or sand. It was completely soluble in dilute hydro- 

 chloric acid with brisk effervescence. Results by qualitative examination showed 

 the excellent quality of this marl. 



CALCAREOUS DEPOSIT. 



No. 13969, Calcareous deposit. From Hedley, B.C. Analysis showed this tn he 

 a mixture of sulphate and carbonate of lime.

Though the percentage of carbonate is not very large, it is nevertheless sufficient 

 to make the deposit of value for correcting sourness in poorly-drained soils. It could, 

 of course, be used on all types of soils, to supply lime, and to act as an indirect fertil- 

 izer.
