Superphosphate of Lime.— When a. small portion of superphosphate of lime 

 is mixed with seeds when sown, in sufficient quantity to give them the ap- 

 pearance of being limed over, the seeds germinate quicker and stronger, more 

 especially in the case of old seeds ; and it is also found that the plants are less 

 liable to damp off, or be injured by insects. — Geo. Gordon. 



Several sorts ofmamtre having been sent to the Garden by their respective 

 inventors, viz. Dr. Hallett's concentrated liquid fertilizer, Harris's liquid 

 manure, and Potter's liquid guano, it was thought desirable to use them in 

 comparison with other kinds of manure, and the following trials were made. 

 Twelve plants of Fuchsia grandiflora were taken from a cutting pan, and 

 potted in 6- inch pots; the soil consisted of peat and loam in equal propor- 

 tions. The first pot was in its natural state ; in the second 1 oz. of charcoal 

 was mixed in the soil ; in the third 1 oz. of charcoal as a top dressing ; in 

 the fourth ^ oz. of superphosphate of lime in \ pint of water; in the fifth \ 

 oz. of superphosphate of lime mixed in the soil ; in the sixth J oz. of phos- 

 phate of ammonia in \ pint of water ; in the seventh -k oz. of apatite on the 

 surface of the soil ; in the eighth ^ oz. of apatite mixed in the soil ; in the 

 ninth one tea-spoonful of Dr. Hallett's concentrated liquid fertilizer in -k pint 

 of water ; in the tenth one tea-spoonful of Harris's liquid manure in ^ pint 

 of water ; in the eleventh one tea-spoonful of Potter's concentrated liquid 

 guano in ^ pint of water ; in the twelfth 1 oz. of cow-dung mixed in the soil. 

 The plants were all placed side by side, and received nothing more for up- 

 wards of four months, except water when they required it. The plant which 

 received Harris's liquid manure and those which had apatite grew much 

 faster than any of the others. Those which had cow-dung and phosphate of 

 ammonia were always darkest in colour. Tiie plant which received Potter's 

 concentrated liquid guano kept lingering on for three months and then died. 

 The result was as follows :

Brocoli. 



Walcheren Erocoli, or Caulijfou-er. — A few genuine seeds of this most 

 valuable production were presented by Mr. Legge, gardener, Bishopsthorpe, 

 by whom the variety was first produced. The heads are large, firm, white, 

 like a very fine Cauliflower, which in fact it closely resembles in appearance, 

 except that the leaves are not so plain as those of the Cauliflower. The 

 difference in constitution must however be very considerable, for it not only 

 stands the winter cold, but likewise the summer drought much better than 

 Cauliflowers do ; scarely a head of the latter could be obtained in the dry hot 

 summer of 1844, and at the same time a quarter of Walcheren Brocoli
