tlie majority of tliem are not worth growing a second time ; and witli tlie excep- 

 tion of this year's new ones, I am of opinion that there is scarcely one of those 

 sent out during the last five years that has proved a decided advance upon those 

 in cultivation previously to that date. I cannot say much of this year's sorts, 

 having only grown Carter's G. F. Wilson and Wi\liams''s Em2)ero7' of the Marrows. 

 They have both proved first-rate peas in their season. G. F. Wilson is a strong 

 robust grower and a most abundant bearer, having the same appearance as 

 Veitch's Perfection, but I think it is a few days earlier, and a little hardier than 

 that fine sort. Emperor of the Marrows is a tall, strong, branching, wrinkled 

 white Marrow, producing an immense crop of fine large pods ; this is very like 

 our old friend British Queen in her true colours ; but be that as it may, it is a 

 first-class sort, well worth growing where large marrow peas are esteemed. 



Having to supply a large establishment where green peas are wanted every 

 day they can be had, I am often sadly taxed as to the best sorts to grow to keep 

 up the supply from May till November. Up to the present time I have not 

 found any to beat the following : — For sowing during November for first crop, 

 Dillistone's Earh/ and Maclean's Little Gem. To sow during December and January, 

 Frizetal-er, which is the only Marrow that I have ever found it safe to sow before 

 February ; Alpha and many of the so-called early Marrows are on the score of 

 hardiness nowhere, compared to Prizetaker. To sow during February and March, 

 Maclean's Prolific and Best-of-aU. To sow during April and May, Veitch's Per- 

 fection^ Emperor of the Marrows, and G. F. Wilson; and in June and July, 

 Maclean's Premier and Ne Plus Ultra. 



On the 20th of June I sowed six quarts of Premier., and on the 4th of July 

 eight quarts of Ne Plus Ultra., and from the beginning of September up to October 

 22nd, (when this is written) we have been gathering from these about a peck 

 nearly every day, and they look as if they would continue for weeks yet, if the 

 weather will only keep open. Such is my experience of Peas, and if any of your 

 readers can recommend better sorts for general garden purposes, I believe they 

 will do a kindness to many others, as well as to — J. McIndoe, PiishoiJsthorpe 

 Palace Gardens. 



AQUATICS.— Chapter XII. 



^OCCASIONALLY the Marsh Cinquefoil, Comarum palustre., a 'mimic Potentil, 

 may be met with in shallow ponds in some of the shady quiet nooks 

 of Old England, more especially northwards. It usually grows to about 

 18 in. in height, the stems being somewhat decumbent, and emitting roots 

 rather freely. The leaves are alternate, sheathing the stem at the base, and 

 consist of five finely-toothed leaflets, which are glaucous beneath and dull green 

 above, and bear no remote semblance to those of some species of wild Eose. The 

 flowers are of a dark chocolate-colour, and in size and form look very like some 

 of the old single Potentillas, rarely exceeding the size of a shiUing ; they are 

 produced through most of the summer months, and the plant becomes deciduous
