^19^' hints respecting domestic economy. \%\ 



I fhall now finifli my letter with a few miscellaneous 

 hints on northern plants, which will probably for that rea- 

 son suit your climate, and which I think merit trial from 

 useful purposes they may be applied to. 



Trifolium bybridum. 

 Do you cultivate in Scotland the best of all our nor- 

 thern* grafses,'' and the most hardy, the trifolium hybri- 

 dum, a most excellent white clover ? *. 



RoBiNiAy^ro.Y, and Ferula asafmtida. 

 Has the robinia ferox succeeded for impenetrable hed- 

 ges, the seeds of which I sent over, with many other Si- 

 berians, to my old correspondent, the late worthy profef- 

 sor of botany f ? I fliould likewise be happy to know if 

 my ferula asafoetida is still alive, and has produced 

 good seeds, of which he was' so proud twelve years ago, 

 when that plant presented the new and curious phenome- 

 non of flowering in Europe, to which it had till thea 

 been a stranger. The true asafoetida was a valuable ac- 

 quisition to Great Britain, if it has been cultivated with 

 succefs J for the good doctor had it growing in the open air, 

 and mentions in the Philosophical Transactions of London 

 (where he has given a fine plate of the plant in flower) 



* Answer : I do not know that it is ever cultivated here. Some of 

 the seeds of it will prove acceptable. 'Edit. 



\ I was so sensible of the value of this plant for the purpose here 

 hinted at, when I read the accounc of it in the Flora Rofsica, lately- 

 presented by the Emprefs of Rufsia to the Royal Society of Edin- 

 burgh, that I wrote by post to Arcticus. requesting the favour of him 

 to procure me some seeds of it. Since receiving the above I have 

 made inquiry for it in the Botaiuc garden ; but do not find it 

 there. Edit.
