Amico carissimo _Johanni Evelyno_, Armigero, e Societate Regali Londini, J. Beale, _S.P.D._ _In_ Silvam. Fare age quid causae est quod tu _Silvestria_ pangis, Inter _Silvanos_, capripedesque _Deos_? Inter _Hamadryadas_ laetus, _Dryadasque_ pudicas, Cum tua _Cyrrhæis_ sit _Chelys_ apta modis! Scilicet hoc cecinit numerosus _Horatius_ olim, _Scriptorum Silvam_ quod _Chorus Omnis amat_. Est locus ille Sacer _Musis, & Apolline_ dignus, Prima dedit summo _Templa_ sacranda _Jovi_. Hinc quoque nunc Pontem _Pontus_ non respuit ingens, Stringitur _Oceanus_, corripiturque Salum. Hinc novus _Hesperiis_ emersit mundus in oris,{cii:1} Effuditque auri flumina larga probi. Hinc exundavit distento _Copia cornu_, Qualem & _Amalthææ_ non habuere sinus. _Silva_ tibi curae est, grata & _Pomona_ refundit Auriferum, roseum, purpureumque _nemus_. Illa famemque sitimque abigens expirat odores, Quales nec _Medus_, nec tibi mittit _Arabs_. Ambrosiam praebent modo cocta _Cydonia_. Tantum Comprime, Nectareo _Poma_ liquore fluunt. Progredere, _O Sæcli Cultor_ memorande futuri, Felix _Horticolam_ sic imitere Deum. FOOTNOTES: {cii:1} Gen. 1. _c._ 2. Nobilissimo Viro _Johanni Evelyno_, Regalis _Soc. Socio dignissimo_.
