Thanksgiving Day Party(感謝祭)



こんにちは,M2の長野です.

先週11月24日に,アメリカから来ている研究生 Lauraの主催で感謝祭(Thanksgiving Day)のパーティーをしました.

イギリスからアメリカに入植した清教徒達の最初の収穫を祝って,現地では毎年11月の第四木曜日に行うものです.今回は国際ロッジの一室を借りて,研究室のメンバー・友達も含めて15名程が参加しました.


感謝祭の由来について説明するLaura

 感謝祭で定番の七面鳥は用意できませんでしたが,参加者でそれぞれ料理を持ち寄った結果盛大なコースになりました!  

 ジャガイモ.サツマイモ,カボチャをふんだんに使ったパイ・スープ等アメリカの伝統的な料理は勿論ですが,日本のスーパーで見かけるお惣菜も提供されています.これも和洋折衷でしょうか?笑


たくさん料理があります!どれもおいしそう!


 ともに過ごすことが出来る恵みと喜びを神に感謝した一日でした!

Tonga Journey (3) サンゴ&鍾乳石採集の巻

こんにちは、いずれ丸焼きにされるであろうブタです!

長らく間が空いてしまいましたが、今回はサンゴと鍾乳石の採集についてお話します。

まずは、サンゴの採集から。
我々が訪れたTongatapu島はほとんどがサンゴ礁からなる島なので、下のように道端にも化石サンゴがゴロゴロしています。

道端に埋まるサンゴ

とは言え、保存状態が良く、ある程度大きな化石サンゴを見つけるには、ある意味運も必要です。
こんな感じ。

さて、デカすぎるカフェラテで身体を温めた我々は、鍾乳洞を案内してくれるガイドさんの元へ。
なんとこれでLサイズ。トンガ人もびっくり。

ガイドさんは、在野で考古遺物の収集をされていて、ご自身のサンプルを基にGeoffさんと議論を重ねていました。

ガンダルフみたいなガイドさん。

鍾乳洞潜入のプランを立て、いざ出陣。まずはハードな鍾乳洞をさっくり紹介。

野山に分け入り入口を捜索
全然見つからないので上からも捜索。ウホッ!
発見、思ったより入口が狭い…
感動の生還!…ではなく潜入しているところ

苦労した割に、土砂で行き止まりになっており先に進むのは断念。次の鍾乳洞へ。

超軽装備で現れたガンダルフ(ガイドさん)

先ほどの鍾乳洞とは異なり、鍾乳石や水をよく採集することが出来ました。



そして、フィールドワークをすると汗をかきますよね…
ということで鍾乳洞の中で水浴び。



サンゴも鍾乳石も(鍾乳洞プールも)初めてづくしで、とても良い経験が出来たと思います!
それでは、M1の福與でした。
