smaller produce than the other. This is due to the fact that, 

 for some reason or other, it was extremely deficient in plants, 

 their number not hems; above half of what it was in the other 

 plots. The details will be found in Tables XII. and XIII. 



Experiments made at Leuchland, Brechin, by Mr. Mustard. 



The soil on which these experiments were made is a good 

 sound loam, resting on clay, situated about 120 feet above the 

 sea level. It was for many years worked under the five course 

 rotation. At present it is under a seven shift course, consisting 

 of three grain crops, two green, and two years grass. No 

 manures have been applied within the last three or four years. 

 In autumn it got a fair furrow with two horses, and early in 

 May vas twice grubbed and cleaned in the usual way. 



The crop was sown on the loth June, the weather being 

 very dry, with strong sun and moderate breeze. The arrange- 

 ment was the same as that in the plan, except that the first 

 nothing plot was between Nos. 5 and G, instead of between 4 

 and 5. 



Rain fell on the 16th, 10th, and 20th, and the braird appeared 

 on all the plots on the 21st. Favourable weather, with heat 

 and occasional showers, followed, till the 21st July, when the 

 crop was thinned. From the loth to the 26th the weather was 

 dry and warm, and the crop went on well, with the exception 

 of Nothing, 10, and 11, which were very poor. 



During the whole of August and September the weather was 

 very wet. 



The crop was weighed on the 5th December. The results 

 are contained in Tables XIV. and XV. 



Experiments made at West Drums, Brechin, by Mr. W. Smith. 



The field on which these experiments were carried out is a 

 light sandy soil, having a porous rocky subsoil, interspersed with 

 beds of sandy clay, and resting on the old red sandstone. It is 

 300 feet above the level of the sea, and has a south-westerly 

 exposure. The field had been for three years in grass, pastured, 

 and two years oats, before the grain crop of 1866. The second 

 crop of oats got 2 cwt. Peruvian guano, and 1 cwt. of salt per 

 acre. The poorest portion of the field was selected for the ex- 

 periments, in order to give as fair a result as possible. The soil 

 is easily made for turnips, and the season was favourable to their 

 growth on it, but on all heavy lands in the neighbourhood it 

 was quite the reverse — the severe drought in the early part of 

 the season having prevented their brairding. 



The seed was sown on the 18th June, and the crop brairded 

 very regularly, and w T as thinned on the 15th July, l'lots 1, 2>
